Features are properties of the data like, the number of points, the number of paths, the width of the drawing, the height and so on. Machine learning relies on features extracted from the data.

In this video I'll teach you how to use JavaScript to extract features from our samples and feature them on a chart. First I'll show you how to use a Google Chart and then we use a custom chart we'll build in the next video!

⭐️HOMEWORK⭐️
Extract 2 other features from the data. Share screenshots and your code on my Discord server:

Draw for me :-) I will use your data in the future:
