{"version":"1.0","type":"rich","title":"[Working with spatial data](https://github.com/enjalot/wwsd)","description":"A choropleth of world countries and populated places, rendered as SVG paths and circles, responds to mouse interaction. Hovering a circle highlights it and shifts all other circles ten pixels along the x-axis while recoloring them blue, demonstrating dynamic spatial selection. The visualization loads GeoJSON data from local files and uses `d3.geo.winkel3()` for projection, `d3.geo.path` for country outlines, and manual coordinate projection for circle placement. Built with d3.v3 and TopoJSON, it shows basic event handling with `mouseover` and `mouseout`.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-f8b6d112ec1f1e0b2e5513525d85d499?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
