This is an example post with some geojson code. The support is provided thanks to Leaflet. To create your own visualization, go to geojson.io.

```geojson
{
  "type": "FeatureCollection",
  "features": [
    {
      "type": "Feature",
      "properties": {},
      "geometry": {
        "coordinates": [
          [
            [
              -60.11363029935569,
              -2.904625022183211
            ],
            [
              -60.11363029935569,
              -3.162613728707967
            ],
            [
              -59.820894493858034,
              -3.162613728707967
            ],
            [
              -59.820894493858034,
              -2.904625022183211
            ],
            [
              -60.11363029935569,
              -2.904625022183211
            ]
          ]
        ],
        "type": "Polygon"
      }
    }
  ]
}
```

Which generates:

{
  "type": "FeatureCollection",
  "features": [
    {
      "type": "Feature",
      "properties": {},
      "geometry": {
        "coordinates": [
          [
            [
              -60.11363029935569,
              -2.904625022183211
            ],
            [
              -60.11363029935569,
              -3.162613728707967
            ],
            [
              -59.820894493858034,
              -3.162613728707967
            ],
            [
              -59.820894493858034,
              -2.904625022183211
            ],
            [
              -60.11363029935569,
              -2.904625022183211
            ]
          ]
        ],
        "type": "Polygon"
      }
    }
  ]
