{"version":"1.0","type":"rich","title":"Almost Final-1","description":"This visualization plots GDP variation over time for the USA and Germany, with each country represented by a colored circle. Users can click legend items to highlight a specific country while dimming others. The chart uses D3 v5 with `scaleLinear`, `axisBottom`, and `axisLeft` to render the scatterplot and a custom `colorLegend` that supports interactive selection. Data is loaded asynchronously via `d3.csv` from an external file, and the visualization renders to SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/121d398f924a49709bdcc40514d982bf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
