{"version":"1.0","type":"rich","title":"Fork of Marks and Channels","description":"This fork of Marks and Channels demonstrates fundamental D3 visualization concepts by plotting a small dataset of seven countries according to their personal freedom and capital scores. The visualization uses circles as point marks, with horizontal and vertical positions encoding the two metrics, while circle radius encodes the average of both scores and color distinguishes countries using `d3.scaleOrdinal` with `d3.schemeCategory10`. The implementation shows a bubble chart built with SVG circle elements, `d3.axisBottom` and `d3.axisLeft` for axes, and linear scales for positioning. Country labels are placed inside each circle using SVG text elements. The code illustrates scaling factors, SVG attributes `transform` and `fill`, and D3 color schemes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/45f16f69ac5d4abea7f71e0504f866d6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
