{"version":"1.0","type":"rich","title":"yunnanMap with Selectable Countries","description":"This example visualizes a choropleth map of Yunnan Province, China, with selectable countries. The map encodes a categorical color value (`yszl`) using an ordinal color scale with a spectral scheme, and users can click individual countries to highlight them and dim the rest. A color legend allows filtering by color value. The visualization uses D3 v5’s `geoPath`, `geoMercator`, and `zoom` modules to project and render GeoJSON features, while the legend and map interactions are built with D3’s selection and event APIs. Data is loaded from external CSV and JSON sources.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/02dc49c5f6224dbbb7d828026ca6be3a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
