This example shows two distinct data visualizations in one page: an area chart tracking monthly salaries across 2023, and a pie chart displaying browser market shares. The area chart uses D3’s `d3.area` generator with time-scaled axes and explicit axis labels, while the pie chart loads CSV data via `d3.csv`, applies a `d3.pie` layout, and renders arcs with `d3.arc` and a color scale. Both visualizations rely on SVG rendering and D3 v6, with the pie chart adding an interactive legend.
