You can place any number of "leafet items" inbetween the `leaflet_map` tag blocks. At minimum, there must at least be an empty object `{}` in between the tag blocks, or else the map won't draw at all. Leaflet items include markers, geometries, geojson, features, popups, etc. Each leaflet item tag also takes in a single JSON object positional argument. In this example, we will be drawing 1 marker and 1 Polygon on a map.

Leaflet items include markers, geometries, geojson, features, popups, etc. Each leaflet item tag also takes in a single JSON object positional argument. If an `id` key is present inside the `properties` object, its content will be used as the id of the ̀<path>` tag which represent the geojson element on the map. In this example, we will be drawing 1 marker and 1 Polygon on a map.
