Heatmap Matrix
Interactive square heatmap for visualizing pairwise relationships. Inspired by the Binary Phase Diagram Map from the Sun Research Group.
Element Pair Electronegativity Difference
Full 118-element matrix colored by |ΔEN|. Elements without electronegativity data
(noble gases, some superheavy) are auto-hidden with hide_empty="compact".
Hover for tooltips, click cells for details.
Symmetric Subset with Custom Tooltip
20 metals with switchable symmetric mode (lower/upper/off) and interpolatePlasma color scale. Custom tooltip shows element names and electronegativity values.
Double-click updates the status text below. Use the controls (gear icon) to toggle
symmetric mode.
Arbitrary Axis Items
Axes don't have to be elements. This demo uses property-range bins as both axes, showing
that HeatmapMatrix works with any AxisItem[]. Uses interpolateYlOrRd color scale and a custom cell snippet that renders the value
inside each tile.
