{"version":"1.0","type":"rich","title":"Cheap Tricks for Interaction","description":"This example demonstrates a zoomable, pannable world map projection using D3.js, where countries are rendered as SVG paths and labeled on demand. The visualization loads geographic data and applies a custom equirectangular projection with a northern center, then uses D3’s `d3.zoom` and `d3.event.transform` to enable smooth scaling and panning interactions. Country highlighting and label backgrounds are styled via CSS classes such as `.country-on` and `.countryLabelBg`, while the map initially hides all labels until zooming or selection occurs.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ca99387253844018a98aa66c65a96f72?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
