{"version":"1.0","type":"rich","title":"Median household income by Oregon county","description":"The visualization maps median household income across Oregon counties, using color intensity to reveal regional disparities, from the highest earners in Clackamas and Washington Counties to the lowest in Grant and Lake Counties. It shows a static choropleth of the state, with each county polygon filled according to its income value. The code uses `d3.csv` to load the income data and `d3.geoPath` to render county boundaries from a GeoJSON topology, while a sequential color scale maps income ranges to fill colors. The data originates from a gist by ajzeigert, with the overall Oregon figure included for reference.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-c0a2f625888dde3150b4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
