{"version":"1.0","type":"rich","title":"Election Data Scatterplot","description":"Each dot in this scatterplot represents a U.S. presidential election, comparing the winner’s margin of popular vote victory (horizontal axis) with a rating of presidential effectiveness from the 2014 APSA survey (vertical axis). Circles are colored by the winner’s party, and hovering reveals a tooltip with the winner, party, year, and runner-up. The axes use percentage scales, and the chart includes a title and a legend. The visualization is rendered in SVG with D3 v4 and animated hover interactions. The author notes the original premise—that higher-rated presidents should have larger victory margins—is flawed, as each election is a unique contest; the data shows a 0.15 Pearson’s r correlation between margin and rating.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-571bb54d69478f05d290d2c301b70e05?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
