{"version":"1.0","type":"rich","title":"Fork of Fork of Fork of Fork of Heatmap in D3","description":"This visualization displays the adjacency matrix of a dolphin social network, showing connections between individual dolphins as blue cells against a white background. It loads real network data from a GitHub Gist using `d3.text`, parses the edge list, and builds a symmetric matrix to reflect the undirected graph. The code uses core D3.js v7 methods like `d3.select`, `selectAll`, and `data().enter().append()` to render the SVG rectangles, with row groups positioned via `transform` attributes and cell fills determined by binary connection values. Tooltips are included but not bound to mouse events in the provided code.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fce9d89bce684d67bc970bfe4e552fd1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
