{"version":"1.0","type":"rich","title":"GDELT CAMEO Codes","description":"This visualization maps the hierarchical structure of GDELT CAMEO event codes, showing how broad categories like \"Appeal\" or \"Provide Aid\" branch into increasingly specific sub-actions. It uses a radial tree layout powered by `d3.forceSimulation` for node positioning and `d3.hierarchy` to parse the CSV data, with nodes colored by their top-level category. The code renders the tree using SVG paths via `d3.geoPath` for curved links and displays each event’s description as a label. The source file `gdelt-cameo-codes.csv` provides the two-column code-and-description pairs that drive the layout.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-71096cb85e4677fb79635aad5d1f4303?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
