Grainline — paste-a-feed dashboard
Paste any CSV, TSV or JSON feed and Grainline instantly draws a remixable dashboard: field types auto-detected, stat tiles, plus line/area/bar/scatter charts, a distribution histogram and a category ranking — all with hover tooltips. Everything runs locally, and a Share link encodes your feed and field choices so anyone can open the exact board and make it their own. Export the main chart to PNG or the cleaned data to CSV.
