{"version":"1.0","type":"rich","title":"d3v3 Multiple Pie Charts on Map - Static Data","description":"This example overlays multiple small pie charts on a world map, with each pie positioned at a geographic coordinate from a CSV file. The map uses a Mercator projection centered on India, with countries rendered as green landmasses and white borders via TopoJSON. Each data point is plotted as a small pie chart using d3.layout.pie and d3.svg.arc, with slices colored by category10 scale; a red dot marks each location. The visualization combines geographic context with proportional composition, illustrating how static CSV data can be overlaid onto a map using D3 v3 and SVG.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-7e06e7522796f36e4e278ab72fc0d877?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
