Naruto Power Levels Over Time (1 Second = 1 Episode)

DataDaft 2021-06-14 | Naruto power levels from Naruto 1 through Shippuden 500. Every episode is displayed for approximately 1 second. Note that the video only shows power levels relevant to the current timeline (does not include flashbacks) and it skips long spans of filler episodes. Also note that the video shows a character’s current power level. This means a character that is strong but exhausted, injured or suppressing his power might appear lower than expected.

The concept of “power levels” are not a part of Naruto canon like they are in Dragonball, but I thought it would be fun to make a power level plot video similar to my Dragonball video, showing the flow of the story of Naruto over time as expressed through rough character power levels. Many viewers have expressed interest in such a video.

It is not possible to make a direct translation from Dragonball power levels to Naruto, since the concept of strength in the two shows is different. In Dragonball, power is fairly easy to quantify: the stronger a character is, the more speed, durability and more destructive power they have. In Naruto, power is more nuanced. Fights are more strategic and often based upon techniques like ninjutsu and genjutsu instead of brute force, DBZ style taijutsu and energy projection. The power levels here are meant to roughly fit into the DBZ conception of power level, but Naruto characters will generally have lower durability and raw destructive power than DBZ characters at similar power levels, while having more techniques and abilities.

Also note that one character having a higher power level than another does not necessarily mean they would win a fight. Certain characters counter others with abilities and some characters are able to fight well above their power level due to strategy and preparation. Some characters are capable of drastically raising their power levels for short bursts (chidori, rasengan, opening gates, etc.) which allows them to take down opponents with higher base power levels.

General guide to Naruto power level tiers in this video:

Power Level 0: Unconscious/Dead
Power Level 1-10: Normal Person
Power Level 10-100: Genin Level
Power Level 100-200: Chunin Level
Power Level 200-400: Jounin Level
Power Level 400-800: Jounin+ Level (Strong Jounin)
Power Level 800-1500: Kage Level
Power Level 1500-4000: Kage+ Level (Strong Kage)
Power Level 4000-10000: Demigod Level
Power Level 10000+: God Level

# enumerate() returns a sequence of (index, item) tuples

list(enumerate(characters))

# Use enumerate() in a for loop to get an item and its index

for index, character in enumerate(characters):
print(index, character)

# Why might you want to use enumerate?
# Example: store index positions of duplicate items

characters = ["Krillin","Goku", "Goku", "Gohan", "Piccolo",
"Krillin","Goku", "Vegeta", "Gohan", "Piccolo",
"Piccolo","Goku", "Vegeta", "Goku", "Piccolo"]

character_map = {character:[] for character in set(characters)}

print(character_map)

# Use enumerate to store the index for each occurence
for index, character in enumerate(characters):
character_map[character].append(index)

Game of Thrones: Balance of Power Over Time

DataDaft 2021-04-24 | Data visualization showing the balance of power in Game of Thrones over time . "Balance of Power" in this video essentially means how far a given character is from sitting on the iron throne at any point in time. Note that for all characters other than those actually sitting on the throne, the ranking is subjective. I gave strong precedence to characters with a valid claim to the throne based on lineage, followed by characters with close relations to the current ruler (hand of the king, trusted advisor, etc.) and powerful contenders seeking to claim the throne for themselves.

How To Get Absolute Values in Python

DataDaft 2021-03-26 | abs() is a Python built in function that finds the absolute value of a number. abs() can be combined with map() to get the absolute values of all numbers in a list and abs() can be run on numpy arrays and pandas columns.

Code used in this video:

# Check absolute value with abs()
x = -5
abs(x)

# Calculate the absolute value of every element in a list

x = [4, 5, -3, -6, -2, 6]

[*map(abs, x)]

# Calculate the absolute vaule of an array

import numpy as np

x = np.array(x)

abs(x)

# Get the absolute value of a Pandas column
import pandas as pd

df = pd.DataFrame({"col1":x})

print(df)

abs(df["col1"])

* Note: YouTube does not allow greater than or less than symbols in the text description, so the code above will not be exactly the same as the code shown in the video! I will use Unicode large ＜ and ＞ symbols in place of the standard sized ones.

How To Use all() and any() in Python

DataDaft 2021-03-25 | any() and all() are Python built in functions that let you check whether some iterable object like al ist contains any true values or all true values, respectively. This can be a useful operation when you want to check whether some large sequence conforms to a logical check. any() and all() also treat 0's as false and 1's as true, so they can be run on lists, arrays and pandas data frame columns encoded as indicator variables to check whether any or all of the values are equal to 1.

Code used in the video:

# Check if all elements of an iterable are true with all()

x = [True, True, True]

y = [True, False, True]

z = [False, False, False]

print(all(x))
print(all(y))
print(all(z))

# Check if any elements of an iterable are true with any()

print(any(x))
print(any(y))
print(all(z))

# any() and all() work on 0s and 1s
# 0 = False
# 1 = True

x = [0, 0, 0, 1]

print(any(x))
print(all(x))

# Useful when used with logical operations
import numpy as np

power_level_list = np.array([1000, 4000, 150, 9001, 1500])

any(power_level_list ＞ 9000)

* Note: YouTube does not allow greater than or less than symbols in the text description, so the code above will not be exactly the same as the code shown in the video! I will use Unicode large ＜ and ＞ symbols in place of the standard sized ones.

How To Use zip() in Python

DataDaft 2021-03-24 | zip() is a Python built in that lets you combine two or more iterable objects like lists into groups of tuples. zip() is a convenient way of grouping data in multiple lists together in an elementwise fashion.

*Note: Longitude is misspelled in the video! I corrected this in the code below.*

Code used in the video:

# Use zip() to combine iterables like lists into tuples (elementwise)
# Useful for making separate lists into tuples

latitude = [4,5,6,4,6,2,4,5,6]
longitude = [6,3,6,3,4,5,6,8,5]

[*zip(latitude, longitude)]

# Can operate on more than 2 inputs
altitude = [12,41,15,16,15,23,14,51,61]

[*zip(latitude, longitude, altitude)]

# Zip will only continue up to the length of the shortest input

short = [1,2,3,4]
long = [1,2,3,4,5,6,7,8]

[*zip(short, long)]

# If you want to keep all items, use itertools.zip_longest
from itertools import zip_longest

short = [1,2,3,4]
long = [1,2,3,4,5,6,7,8]

[*zip_longest(short, long, fillvalue=None)]

* Note: YouTube does not allow greater than or less than symbols in the text description, so the code above will not be exactly the same as the code shown in the video! I will use Unicode large ＜ and ＞ symbols in place of the standard sized ones.

How To Use map() in Python

DataDaft 2021-03-24 | map() is a Python built in that lets you apply or "map" a function to each element in a list or iterable object. map() is one of the most useful Python built in functions for data analytics, since you will often be working with large sequence data types that need to be transformed in various ways.

Code used in the video:

# Map lets you apply a function to each element of a list

power_level_list = [1000, 4000, 16000, 150, 9001, 1500]

def greater_than_9000(x):
if x ＞ 9000:
return True
return False

mapped = map(greater_than_9000, power_level_list)

print(mapped)

# Print each mapping

for m in mapped:
print(m)

# Extract mapping into new list

mapped_list = [*map(greater_than_9000, power_level_list)]

mapped_list

# Use map with a lambda function

[*map(lambda x: x ＞ 9000, power_level_list)]

* Note: YouTube does not allow greater than or less than symbols in the text description, so the code above will not be exactly the same as the code shown in the video! I will use Unicode large ＜ and ＞ symbols in place of the standard sized ones. .

Tallest Buildings In History To Scale (1 pixel = 1 meter)

DataDaft 2021-02-26 | Top 10 tallest buildings in history over time (3200BC to 2021) using to-scale building images where 1 pixel on the screen is equal to 1 meter when viewed in full 1080p quality.

Building height for this video is generally "architectural height", meaning the tallest of roof & spire height. The data does not count antennas, which can make certain buildings appear taller than others even if they rank lower. Also note that communication towers and other non-building, non-ancient structures were not included in the plot.

Note that the data set only has one image per building but some buildings change height over time either due to damage or additions. In those cases the building's size may not exactly align to scale with others.

Also note that years in which the top 10 buildings in the world did not change were excluded from the plot. There were some years (and long periods) in history with no new tall buildings in the top 10; skipping those years was the only good way I found to keep the graph moving and interesting.

Data: Custom data set compiled from various sources including:
The Skyscraper Center (skyscrapercenter.com)
SkyscraperPage.com
Wikipedia

Images:
SkyscraperPage.com (Special thanks for to-scale drawings!)

Plotting:
No existing data visualization tools were capable of making this plot the way I wanted, so I made this as a custom data viz in the browser with JavaScript.

Top 150 One Piece Characters by Panel Appearances (Through Chapter 1000)

DataDaft 2021-01-04 | To celebrate the 1000th chapter of One Piece, I created this data visualization showing the top 150 one piece characters ranked by the number of manga panels that they have appeared in throughout the series through chapter 1000.

This is a channel devoted to all things data science from fun data viz videos like this one, to technical coding guides and how-to videos. If you liked this video consider subscribing! ► youtube.com/c/DataDaft?sub_confirmation=1

Data Set:
Pieced together from several online sources as well as manual collection from the One Piece manga for certain parts of the Wano arc. Please note that the data set is likely not 100% accurate as getting an accurate count on all panels is difficult and I'm relying on counts other people have made in the past. Also note that certain characters that appeared in some arcs before Wano but who were ranked outside the top ~170 and have subsequently reappeared may not appear on this chart despite possibly having enough panels that they should appear. Characters this might apply to include: Roger, Drake and Apoo. Also note that some Wano-only characters that do not appear in the video will likely have enough panels to rank in the top 150 by the end of the Wano arc. Characters this could apply to include: Yamato, Page One, Ulti and King.
