{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A D3.js network graph visualizes a hierarchical dataset of experts and strategic technology topics, using color-coded nodes and connecting links. Rendered as SVG, the graph supports zooming via `d3.zoom` and dragging nodes through `d3.drag`, with positions computed by a force simulation. A \"Switch\" button dispatches a custom event, though the graph itself does not visibly change in response, and the code includes a template-prefilled smiley-face title that is not implemented in the visualization.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f219d5ec8ac742a3be0321bcea076bc8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
