Create a line graph from a CSV file in After Effects

Use a CSV data file to create a line graph in After Effects. I'm continuing my series of data-driven animation tutorials with something that pretty much every animator has been asked to do before... a line graph. But this time, from DATA! In this tutorial I'll show you how to create a line based on a pre-made data set using expressions, specifically a "for loop".

The final graphs shown at the end of this video can be seen as part of these stories from The Washington Post:
