{"version":"1.0","type":"rich","title":"Fork of Fork of Heatmap in D3","description":"This visualization shows the social connections among dolphins as an adjacency matrix, where blue cells indicate a link between two individuals and white cells indicate no link. The data comes from a GitHub Gist and is processed by d3.text to parse the CSV-like input. Using D3 v7, the code builds a symmetric matrix for the undirected graph, then renders it as SVG rectangles with d3.selectAll and data joins. A tooltip is included but not actively bound to any user interaction in the visible code.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
