{"version":"1.0","type":"rich","title":"Topic Model Viz","description":"This visualization displays a topic model’s data as a vertical column of small purple squares, with each square’s opacity reflecting the value in the second data column. It reads data from a remote CSV file via `d3.csv`, then renders the first 2,000 records as an SVG using `selectAll('rect')` and `insert('rect')`. Each rectangle is positioned 10 pixels apart, with fixed width and height of 8 pixels. The example uses D3 v5 and demonstrates a simple, minimal approach to encoding quantitative values through opacity.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a362e00c24fb4e3e98a6549dd0669aa8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
