{"version":"1.0","type":"rich","title":"Proportional symbols","description":"A proportional symbol map displays the cost-of-living rank for U.S. states using circles positioned by latitude and longitude. Circle size inversely reflects cost rank through a d3.scaleSqrt, with the most expensive state highlighted in red. The visualization is built with d3.v7, using a d3.geoAlbersUsa projection, and includes an interactive tooltip on mouseover. The underlying data comes from expensive_states.csv, and the chart renders as SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/60d4e1fac2da4dd0be2a6f6482c59774?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
