Create professional density matrices with automatic color gradients
The engine will auto-mix these colors based on the data value.
Paste your CSV or table data below. The engine will read the top row as columns, the left column as rows, and color the numbers!

Easily create professional density matrix charts. A heatmap is the gold standard for visualizing complex grids of data, showing highs and lows through intuitive color intensity.
Select a Low color and a High color. Our mathematical engine scans your table, finds the min and max, and precisely calculates the hex code shade for every single cell.
Never worry about unreadable numbers. We built a custom luminance algorithm that scans the background color of each cell and forces the text to be black or white for perfect contrast.
Just paste a raw CSV or Excel grid! The engine strips the top row for your X-Axis headers, the left column for your Y-Axis headers, and automatically builds the geometry.
Modernize your dashboard. Use the styling sliders to add custom physical gaps between cells, and apply border-radius curves to create a beautiful, app-style aesthetic.
Your complex data matrices are completely private. Because our rendering engine runs natively inside your browser, your numbers are never uploaded or stored on any server.
