generate_area_chart
Generate an area chart to visualize data trends over continuous variables like time, showing overall patterns and cumulative effects. Supports multiple series, stacking, and export to PNG, SVG, or ECharts option.
Instructions
Generate an area chart to show data trends under continuous independent variables and observe the overall data trend, such as, displacement = velocity (average or instantaneous) × time: s = v × t. If the x-axis is time (t) and the y-axis is velocity (v) at each moment, an area chart allows you to observe the trend of velocity over time and infer the distance traveled by the area's size.
