Scatter matrix · Extreme-environment application

Compare every pair of quantitative dimensions as scatter cells with diagonal histograms. Combine container size, input method, display capability, and user preference instead of guessing a device name. Compare mobile, watch, e-paper, monochrome, dot-matrix, and standards-based extreme environments on the same chart.

Extreme environments

Reconfigure for display, input, and device capability

Combine container size, input method, display capability, and user preference instead of guessing a device name. Compare mobile, watch, e-paper, monochrome, dot-matrix, and standards-based extreme environments on the same chart.

Fluid responsive

Reflow axes, legends, descriptions, and controls from the available container size.

Control help

Zoom and pan inspect the rendered surface without changing data axes or values. When playback controls are available, they move through real steps in the order each unique value first appears in the source data.

Use Tab to reach a control and Enter or Space to activate it. With the chart focused, use plus and minus to zoom and arrow keys to pan.

Auto placement compares perimeter candidates and avoids the plot, legend, and other callouts when possible. Explicit placement is preserved with only necessary safety correction. Callout text wraps safely inside the bubble. Long unbroken tokens are visually shortened within the line budget, while the complete source text remains available to assistive technology.
