Spline Chart

Like a line chart but with smoothed curves between data points for a softer, more organic look. Ideal when you want to emphasize general flow and trends rather than precise point-to-point changes.

Best for

  • Showing general trends with a polished look
  • Presenting data where smooth transitions are natural (e.g., prices, metrics)
  • Dashboards and presentations where aesthetics matter

Avoid when

  • Precise point-to-point accuracy matters — smoothing can misrepresent values between points
  • Data has sharp, abrupt changes that should be visible
  • Scientific or technical contexts where exact interpolation is required
