{"version":"1.0","type":"rich","title":"DataViz Project - Third Visualization - Mental Illness Choropleth Map with Linked Line Chart and Color Legends","description":"A choropleth map displays the global percentage of national populations with mental illness for a selected year, with a linked line chart below showing each country's trend over time. Moving the mouse across the chart updates the selected year, redrawing the map's sequential blue color scale and positioning a vertical line on the line chart. The visualization uses React with D3 v5, including `geoNaturalEarth1` and `geoPath` for map projections, `scaleSequential` for coloring, and `scaleTime`/`scaleLinear` for the line chart. Data comes from a CSV of mental health disorders, with country boundaries from TopoJSON.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/85b1c6c793c046efa2b724027bcbb831?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
