{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"This interactive visualization combines a scatter plot and a categorical color legend to show GDP variation across years for the USA and Germany. Users can click a country in the legend to filter the data, highlighting selected points while dimming others. The project uses D3 v5 with `d3.scaleOrdinal` for color assignment, `d3.scaleLinear` for axes, and `d3.axisBottom`/`d3.axisLeft` for tick marks, rendering as SVG from a CSV dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/85b1fc0bf2644b79b16c848d8b70ee6c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
