{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This visualization displays a choropleth map of Iran, coloring each province based on a selected dataset column. A dropdown menu lets users switch between different attribute values, triggering a white flash transition before the new colors settle. The map uses `d3.geoMercator` and `d3.geoPath` to render GeoJSON boundaries, with `d3.scaleLinear` mapping log-transformed data values to random generated colors. A custom `colorLegend` shows the most and least value range, while `d3.zoom` enables panning and scaling of the SVG output.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/041f62106e3c4573aaca5d96a3201fdf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
