{"version":"1.0","type":"rich","title":"SC4","description":"This visualization shows the distribution of grain elevators across South Carolina counties, with each county shaded on a color scale from light yellow to dark red based on the number of elevators it contains. Hovering over a county highlights it in blue and displays a tooltip with the county name and elevator count. The map is rendered using SVG paths from a GeoJSON file, projected with `d3.geoMercator` and `d3.geoPath`, while elevator data is loaded from a CSV. The color scale uses `d3.scaleLinear` with `d3.extent` to set the domain, and tooltips are implemented as a D3 selection appended to the page.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/055986f150f04098a1e568199984ba67?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
