Placeholder Chart Generator

Reserve space for a chart without implying real results

These charts use synthetic values for dashboard and presentation layouts. They do not visualize uploaded data or measured results. Keep a visible “Sample data” label when sharing a mockup, particularly in sales, financial or performance presentations.

Control the visual density

Choose bar, line or pie, then set 2–20 points and dimensions from 100 to 2,000 px for SVG. PNG output caps each side at 1,000 px; larger requests produce a smaller image. A detailed PNG can still exceed the API response limit, so reduce dimensions or use SVG when a size error appears. Use a small point count for a compact card and a larger count to check crowded layouts. Change the seed to get another arrangement. The title is optional and appears inside the generated image.

Save a stable fixture

SVG suits browser layouts; PNG fixes the pixels for tools that expect raster images. Reusing the same settings and seed produces repeatable output within the current implementation. Save a file if a screenshot comparison must remain unchanged after service updates. For related table layouts, try the data generator; for decorative dashboard backgrounds, try SVG backgrounds.
