{"version":"1.0","type":"rich","title":"汇总","description":"This dashboard presents a four-panel visualization of CDC ILINet flu surveillance data, showing weekly patient visit metrics across years and US states. It includes a line chart of annual trends, a choropleth map of state averages, a bar chart of top states, and a colored line chart tracking those states over time. Built with React and D3 v5, the example uses `scaleOrdinal` for color mapping, `geoAlbersUsa` and `geoPath` for map rendering, and `scaleBand`/`scaleLinear` for bar and line axes. Data is loaded via `d3.csv` and `d3.json`, with interaction implemented through React state and D3 event handlers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a2f52eb323b14f23a3bfe0e85c7eabcc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
