{"version":"1.0","type":"rich","title":"Cheap tricks for interaction","description":"A world map rendered with D3's geoNaturalEarth1 projection and SVG paths shows country boundaries as light green shapes over a dark blue sphere. Interactive tooltips appear when hovering over a country, and the fill color changes to red on hover via CSS.
