{"version":"1.0","type":"rich","title":"Bar Chart with Highlighting","description":"This bar chart displays 2018 population data for the ten most populous countries, with each bar color-coded by population size threshold. The visualization uses D3 v6 with SVG rendering, employing `scaleLinear` and `scaleBand` for axes. Bars change opacity on mouseover and show a tooltip with country and population values via D3 event handlers. Data loads from a CSV file using `d3.csv`, and population values are multiplied by 1000 to convert from thousands.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/70f13a55a7b7438f94cdb1521b326229?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
