This line chart visualizes world stock market trends over time, plotting yearly values as a smooth, orange curve against a grid of axes. The data is loaded from a CSV file and rendered as an SVG element. Built with D3 v5, the example uses `scaleLinear` for both axes, `line` with `curveBasis` for the path, and `axisBottom`/`axisLeft` for tick marks, with labels for year and stock market value.
