{"version":"1.0","type":"rich","title":"A8- Adj Matrix","description":"This example renders an adjacency matrix from a bitcoin transaction dataset loaded via `d3.csv`. Each cell represents a connection between two nodes, with transparency indicating the presence of a link and blue fill for edges. The visualization uses D3 v7 with SVG `rect` elements, computing the matrix from unique node pairs. Hovering triggers a `mouseover` event, turning cells red and displaying the edge weight in a temporary HTML tooltip appended to the body.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a427d3a9f5ab4bec873dfdf4b98c2850?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
