{"version":"1.0","type":"rich","title":"A8 - adjacency matrix","description":"This example visualizes a Bitcoin transaction network as an adjacency matrix, where rows and columns represent nodes and cell opacity reflects link weight. The SVG rendering uses D3.js v7 to load CSV data, construct a symmetric matrix, and generate individual `<rect>` elements sized proportionally to the matrix dimensions. Hovering over a cell highlights it in red and displays the corresponding weight value as a temporary text label near the cursor, while mouseout restores the blue fill and removes the tooltip.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/85c18a217db64bb2984e7e1a95caa285?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
