A force-directed bubble chart displays cars from the classic Motor Trends dataset, grouping models by brand origin (domestic, Japanese, or European) into colored clusters. The SVG visualization encodes each car's horsepower as the circle radius and labels nodes with truncated model names, while acceleration and MPG values are excluded from the visual mapping. Built with D3 v3, the layout uses `d3.layout.force` with custom cluster and collision functions to separate groups while preventing overlap. The ordinal color scale assigns blue, red, and gray to the three regional categories.
