This example uses D3 v5 APIs within a React component to render a multi-series chart combining bars and a line. D3’s `csv` loader, `scaleBand`, `scaleLinear`, `line`, and `curveMonotoneX` construct the visualization, which plots M2 Money Supply as bars and GDP as a line over time. The data comes from a remote CSV file, and the SVG rendering includes interactive features, tooltips, and hover effects with drop shadows. Axis ticks and labels are built via custom React components using D3 scales.
