This example displays a line chart of average life expectancy over time, with yearly values plotted along the x-axis and the corresponding life expectancy on the y-axis. The visualization uses D3 v5 with SVG rendering, employing `scaleLinear`, `scaleTime`, `axisBottom`, `axisLeft`, and a `line` generator with `curveBasis` for smooth interpolation. Data is loaded from a CSV file containing stroke-related statistics, and axes are annotated with labels and a title. The line is styled as a thick orange stroke within a margin-based layout.
