Sparks

Thirteen shapes. One number each. Metric, sparkline, progress, status, counter, gauge, table, feed, distribution, leaderboard, timeline, map, or a custom API payload.

You describe the spark. Sparkboard picks a type from the query shape, binds a Source, and stamps freshness on every reading. Push a value and it lights up in about a second.

Sparks are not charts of everything. They are the number you actually look at — with a delta, a source, and a clock.
