<link rel="stylesheet" href="assets/vendor/libs/leaflet/leaflet.css" />

Include the following vendors script in the "Vendors JS" area from the page's footer:

<script src="assets/vendor/libs/leaflet/leaflet.js" />

<div class="leaflet-map" id="basicMap"></div>

const basicMap = L.map('basicMap').setView([42.35, -71.08], 10);
L.tileLayer('https://{s}.tile.osm.org/{z}/{x}/{y}.png', {
  attribution: 'Map data &copy; <a href="https://www.openstreetmap.org/">OpenStreetMap</a>',
  maxZoom: 18
}).addTo(basicMap);

<div class="leaflet-map" id="shapeMap"></div>

const markerMap = L.map('shapeMap').setView([51.5, -0.09], 12);

const circle = L.circle([51.508, -0.11], {
  color: 'red',

  fillOpacity: 0.5,
  radius: 500
}).addTo(markerMap);
