{"version":"1.0","type":"rich","title":"Untitled","description":"The chart demonstrates why mapping values linearly to circle radii distorts data, using four strategies in a horizontal dot plot. Groups with 10, 30, 50, and 100 show that linear radius scaling makes larger values appear disproportionately small, while a square-root-adjusted radius or linear area scaling preserves proportional perception. The visualization uses D3 v5 with `d3.scaleLinear`, `d3.scalePoint`, and `d3.axisTop` to compare encodings, highlighting area as the correct perceptual channel for bubbles.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/07ccaacc440b41b78d5163d1e6ccd26a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
