Announcing The Chart Starter Series

So, hey, heads up: The Chart Starter Series is probably not for you. If you know my work well, you are probably already a dataviz whiz. The Chart Starter Series is for your colleague. You know the one. The one who keeps asking you to make their graphs. Tell them about...
