Online Wiring Diagram

I started by drawing the Venn diagram using Adobe Illustrator. I first created the overlapping shapes using the pathfinder tool. Next, I added a lot of points on my circle so that the curved edges would look smooth in Tableau. Illustrator uses vector files that use Bezier curves to draw a smooth line in between points, but a polygon in Tableau can only draw straight lines between coordinates. Thankfully you can add more points in Illustrator by selecting the shapes then Object Menu > Paths > Add Anchor Points. Each time you add anchor points, it essentially doubles the number of points on the shape. I found that doing this seven times created a high enough resolution to use in Tableau. Any more, and the amount of points would cause the viz to slow down, any less and the image looked choppy. After adding points, I used this technique by Brian Prestige to grab the coordinates of the points from the Illustrator file and format them to use as polygons in Tableau. I used an Alter...
