This bubble chart visualizes data from a provided CSV file, using a force-directed layout to position circles whose size and color encode the dataset’s quantitative dimensions. The chart is built with D3 v7, leveraging `d3.forceSimulation` for the layout and standard SVG elements for rendering. Interactive hover effects increase opacity and stroke width, and a tooltip provides additional detail. The visualization relies on a local CSV file, with styling defined in an external stylesheet.
