{"version":"1.0","type":"rich","title":"Test Chloropleth","description":"This visualization displays the number of data points across U.S. states in a hexagon tile grid choropleth. The color scale uses a threshold encoding with d3.scaleThreshold and d3.schemeBlues to represent counts from the StateFile.csv dataset. The map is rendered using d3.geoPath and TopoJSON, loading US state hexgrid geometry from a GitHub-hosted GeoJSON file. A legend with an axis provides reference for interpreting the color values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a79b181e468c41eca22c763f8666f13c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
