A collection of circles drawn with Svelte and D3 displays a static scatterplot on a gray SVG canvas. Each circle’s x and y positions are mapped from fixed data coordinates using `d3.scaleLinear`, while its fill color and radius come directly from the dataset. Clicking a circle highlights it with a red stroke by comparing the clicked datum against the current selection. The example demonstrates how to mix Svelte’s reactive bindings for container dimensions with D3’s scale functions for coordinate mapping.
