Fun With SAS ODS Graphics: All-Star Baseball-like Donut Charts



Seeing Chevell Parker pull-donut-charts-out-of-a-SAS-Excel-hat at SASGF 2017 made me try to recall, "When did I see a donut chart for the first time?" Well, SAS/GRAPH users have had donut charts in their bag-of-dataviz-tricks for about a quarter of a century. But that wasn't it. Even earlier users of donut charts, including me, were kids who grew up playing the sadly-discontinued Cadaco All-Star Baseball board game, where pie-charts-with-a-hole-in-the-middle were used to present MLB batting stats on game discs since 1941. So, after reading Prashant Hebbar and Sanjay Matange's SASGF paper on Easy Polar Graphs with SG Procedures, I thought to myself, "Could I use SAS ODS Graphics to create All-Star Baseball disc knock-offs?"

Nice!  You could also make it interactive with d3.js (one of my favorite js libraries):

A spinner would be fun! Smiley Happy
