This example shows the crime index across different countries over time, with the data plotted as a smooth, orange area chart. The chart uses D3 v5 APIs including `scaleTime`, `scaleLinear`, `axisLeft`, `axisBottom`, and `area` with `curveBasis` to create the filled curve. It is rendered as an SVG inside an HTML page, and the data is loaded from a CSV hosted on GitHub, with axis labels and a title styled via CSS.
