Build an interactive earthquake map

the prompt

You're a data journalist building an interactive earthquake explorer. Your raw data is the attached file earthquakes.csv — 1,100 events over 12 months (time, latitude, longitude, magnitude, depth_km, place). Build a single self-contained HTML page: an interactive world map plotting every quake, sized and colored by magnitude; a time scrubber that plays through the year; a magnitude filter; and a side panel listing the largest events + summary stats (total count, biggest event, most active region). Draw the world map yourself (a simple equirectangular outline is fine) — no map libraries, tiles, or external assets. Derive everything from the data. Vanilla JS + inline SVG/canvas. Return only the HTML.
