{"version":"1.0","type":"rich","title":"Fork of Observable Plot Starter","description":"This example uses Observable Plot to visualize changes in income inequality across U.S. metropolitan areas from 1980 to 2015. Arrows connect each metro’s position on a logarithmic population axis against an inequality index, with stroke color encoding the change in inequality. The chart includes labeled highlights for select cities, and the code parses CSV data with string-to-number conversion. Plot's `arrow` and `text` marks render the visualization, with dimensions measured from the container to support hot reloading.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/21c2ef94794c4fe388a2f8ba499ec0dc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
