{"version":"1.0","type":"rich","title":"NYC Crash Point Map with interactive legend","description":"A map of New York City displays crash locations as small black dots over borough polygons, each tinted with a distinct color. An interactive legend lets users hover over a borough name to highlight its corresponding region and dim others. Built with React and D3, the visualization uses `d3.geoMercator` and `d3.geoPath` to project and render the TopoJSON-derived borough boundaries, while crash coordinates from a CSV file are plotted as SVG circles. Hovering a legend item dims non-matching boroughs and intensifies crash point opacity for the selected area.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e8f2be845ce9472a88a34caf1716ce5a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
