{"version":"1.0","type":"rich","title":"72. D3 On Combo Transition","description":"Clicking the text triggers a transition of 50 randomly generated data points in a scatterplot, rendered as SVG circles with D3 axes. The chart uses `d3.scaleLinear` to map values and `d3.axisBottom`/`d3.axisLeft` for scales. Upon click, `d3.select` updates the dataset, recalculates axis domains, and calls `.transition()` with a 1000-millisecond duration. The code chains `transition.on(\"start\", ...)` to turn circles magenta and enlarge them, then `transition.on(\"end\", ...)` to trigger a second transition that restores black and shrinks them back.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3c85bf5cebe34f329b8fa5652d07557c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
