This animated scatter plot demonstrates smooth transitions when updating data-bound circles, using D3 v7’s data join with enter, update, and exit selections. Circles scale from zero radius on entry and fade out on removal, while axes animate via d3.axisLeft and d3.axisBottom within a 1000ms transition. The chart applies linear scales for x and y values, with customizable margins and radius. Rendered in an SVG with a styled white background and rounded corners, it shows how reusable chart functions can encapsulate interactive behavior.
