{"version":"1.0","type":"rich","title":"d3 circle practice","description":"A scatterplot displays 50 randomly generated data points as small black circles on an SVG canvas, with teal axes and tick labels. Clicking the prompt above the chart generates a new random dataset, triggering a transition where circles grow to magenta, scale based on their y-values via `d3.scaleSqrt`, and then shrink back to black after the axes update. The code uses D3 v4 with `d3.axisBottom`, `d3.axisLeft`, and `clipPath` to constrain drawing, animating position and appearance through `transition().duration()`.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-b55abfa6bad0ce96b9637070d07bd832?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
