Bookmarked 50 Hours to Draw Some Lines by Doug MacDowell.

Doug MacDowell writes about drawing data visualisations completely by hand. “What are you working on these days?” “Data visualizations.” I told him. “Ah, you using algorithms, machine learning, cloud computing, things like that?” “No.” I said. “I’m just trying to draw a line graph.” My neighbor thought I was getting into some complex sh**. But what’s been more interesting to me lately than using […] is learning to draw data by hand. 50 Hours to Draw Some Lines is about spending more than a week on something that software can accomplish in 20 minutes - and a catalog of resources and methods acquired along the way.
