{"version":"1.0","type":"rich","title":"Fork of Observable Plot Starter","description":"This example uses Observable Plot to visualize changes in income inequality and population across 59 US metro areas from 1980 to 2015. It renders a scatter plot with logarithmic x-axis, where each city is an arrow mark showing the shift from its historical to current values. A color legend encodes the change in inequality, and labels highlight select metropolitan areas. The chart is built with `Plot.plot`, `Plot.arrow`, and `Plot.text`, reading data from a CSV file, with margins explicitly set for the `figure` element and dimensions computed from the container for responsive refreshing.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d79dcfce91b1489daf4f86134d6b9741?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
