{"version":"1.0","type":"rich","title":"nested test","description":"This example shows a small table and an SVG text hierarchy built from a CSV file. The table renders a 4x4 matrix, transforming each cell value by adding its row index multiplied by two. The SVG displays nested text elements, first grouping months by the `cat` column using `d3.nest`, then attempting to append a second level of text based on the group index. The code uses `d3.select`, `d3.csv`, `d3.nest`, and SVG `text` elements, with data loaded from `data.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/95dbaa71d9d24167b4d508f58c36ec3d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
