Area charts combine line charts with filled regions below the line, emphasizing the magnitude of change over time. Stacked area charts show how multiple series contribute to a total. They are effective for displaying revenue streams, traffic sources, resource consumption, and any data where the volume matters as much as the trend. viz42 generates area charts from natural language data descriptions.
Use area charts when the volume or total amount matters, not just the trend. Filled regions emphasize the magnitude of values, especially in stacked layouts.
Describe multiple data series and mention 'stacked' in your prompt. viz42 will generate stacked series showing how each contributes to the total.
Mermaid's xychart-beta supports line charts. viz42 approximates area charts and the exported SVG includes the filled region styling.
