This example shows a static scatterplot of San Francisco arrest records, with each point representing an individual incident. The visualization uses a force-directed layout via `d3.forceSimulation` to position the points, which are rendered as SVG circles through `d3.select` and data joins. The data is loaded from a gist, and the chart arranges points without axes or geographic mapping, focusing on the clustering of arrests. The code relies on d3.v4 and SVG elements within a fixed 960×600 canvas.
