What your data should look like
One row per cell, or a grid with row labels down the side and column labels across the top. Each cell holds a number. Typical uses are correlation matrices, gene expression tables and survey results by group.
SimplePub reads CSV, Excel, TSV, JSON and Parquet files.
What you get
- Sequential and diverging colour scales that print well in greyscale
- Row and column labels that stay legible on dense grids
- Optional values printed inside each cell
- Vector export (SVG, PDF, EPS) for papers, plus PNG for slides
