{"version":"1.0","type":"rich","title":"Fork of Let's make a map with D3.js!","description":"This visualization combines a D3.js v4 Mercator projection map of world countries with layered pie charts representing water quality data from a CSV. The map renders landmasses in green with white mesh borders, while each data point uses a red circle and an overlaid pie chart built with `d3.pie` and `d3.arc`. Country boundaries are generated using the `topojson` library on a world-atlas GeoJSON source, and the pie charts’ angles reflect the comma-separated values in the `data` field. The color scheme for the slices comes from `d3.schemeCategory10`.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/9c52c6f95f98466799ee9053885603db?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
