It answers &ldquo;where are my documents concentrated?&rdquo; in one request, handing the map a count per cell instead of thousands of individual markers.</p> <h2 id="how-it-works"> How it works <a class="anchor" href="#how-it-works">#</a> </h2> <p>Each document&rsquo;s point is encoded as a geohash string: base-32 characters produced by interleaving longitude and latitude bits over successively halved intervals. <code>precision</code> is the number of characters kept — 1–12, clamped, default <code>5</code> (cells of roughly 4.9 km × 4.9 km). The classic Amsterdam coordinate <code>52.374081, 4.912350</code> at precision 3 lands in cell <code>u17</code>.</p>
