Spline Graph
A spline graph is a type of line chart that uses a smoothing algorithm to create a curved line connecting the data points, rather than straight lines. Use the slider on the plot area to adjust the level of smoothness.

The prompt below can be used to build this chart with AI. For best coding results, use the most advanced AI models, like Claude Opus 4.6 and GPT-5.3-Codex. For more info and tips, check out amCharts AI docs.
Create a spline (curved line) chart with ~15 daily data points using smoothed line segments. Display circular bullet markers at each point. Add an interactive slider control that adjusts curve tension between 0 and 1. Include an XY cursor with tooltips, horizontal scrollbar, and pan/zoom on the X-axis. Animate on load. Use amCharts 5 library.
