{"version":"1.0","type":"rich","title":"Gist 3163949","description":"This visualization maps development projects and their work areas as geographic points, connected by curved links to the responsible agencies. It displays project details, budgets, and topic classifications, with agency positions marked as separate nodes. The map uses CartoDB’s SQL API to query project, solution, agency, and topic tables, then renders GeoJSON geometries through D3’s `d3.geoPath`. Node positions are computed via `d3.forceSimulation`, while centroids for work-area polygons are calculated with PostGIS functions (`ST_Centroid`, `ST_X`, `ST_Y`).","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-3163949?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
