Dashboard KitDashboard

This demo runs sample data for a fictional coffee shop in your browser. It opens in English here; press 日本語 at the top right to switch to Japanese.

Filter by period and category, and the numbers, line chart, bar chart, target, and table below all update together. Hover over the line chart and a vertical guide follows, showing that day’s values at once. Every chart can switch to a table view; tables sort when you click a header and download as CSV. Filters are kept in the URL, so you can share exactly the same view.

There are five building blocks (numbers, line, bar, target, table), and the configuration decides what goes where. No chart library and no BI subscription; the colors are an 8-color palette that stays distinguishable for all types of color vision. It works with the keyboard alone, on phone-sized screens, and in dark mode.

Three ways to deploy: embed it in your current site with a few lines of HTML, use the Next.js template (the data location is never exposed to the browser), or publish straight from Google Sheets (visible only to people who can view that spreadsheet). All three show the same screen.
