Earthquakes as a heat map that grows (or pins that appear)

A month of USGS earthquakes as Pulse particles round the Pacific, with a clock, counters and a histogram (this tutorial's particles option).

1. A World map (Robinson or Mercator).
2. Data → Import a file → Open data… → USGS earthquakes, Past 30 days, 2.5 and over, Fetch (about 2,000 points).
3. Heat map: Build it as An image, Radius (km) from the map, Colours Heat, Weight by mag, Grow by time over 5 s. Add heat map (a PNG sequence that fills up). Or Live (particles) for a heat map drawn by the effect.
4. Or Pins with Appear by time: each quake pops in at its time. Or Animate as particles → Events with the Pulse look: a flash where each strikes.

With Atlas MCP: open_data with source: "usgs", period: "month", as: "heatmap", columns: { value: "mag", time: "time" }, over: 5; or as: "particles", kind: "events", look: "pulse".
