 | Data Mime Type | Location Data | Geo Location Processing Description |
 | --- | --- | --- |
-| `application/geo+json` | [Point](https://www.rfc-editor.org/rfc/rfc7946.html#section-3.1.2) | `GeoJSON` Location `Point` coordinates are displyaed as clustered markers using [`leaflet.markercluster`](https://github.com/Leaflet/Leaflet.markercluster) JavaScript library with custom marker cluster icons and config. |
-| `application/json` | Objects that contain Geo location property pairs ending with: `latitude`/`longitude`, `lat/lng`, or `lan/lng`| Flat `JSON` data objects and arrays are processed by our custom [`GeoConverter`](https://github.com/RandomFractals/vscode-leaflet/blob/main/src/renderer/geoConverter.ts) to extract Location information and covert loaded dataset to `GeoJSON` for display on the map. |
-| `text/csv` | `CSV` data with column names in the 1st header row and columns ending with: `latitude`/`longitude`, `lat/lng`, or `lan/lng` | `CSV` data is parsed with [d3-dsv](https://github.com/d3/d3-dsv) JavaScript library and converted to flat `JSON` data array and then to `GeoJSON` with our [`GeoConverter`](https://github.com/RandomFractals/vscode-leaflet/blob/main/src/renderer/geoConverter.ts) to display locations on the map. |
-| `application/vnd.code.notebook.stdout` or `text/plain` | Location data as `string` in `CSV`, `JSON` or `GeoJSON` data format as described above | Text data typically comes from display and [`console.log()`](https://developer.mozilla.org/en-US/docs/Web/API/console/log) instructions in vscode notebooks. We try to parse text as `JSON` with [`JSON.parse()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse) or as `CSV` with [d3-dsv.csvParse()](https://github.com/d3/d3-dsv#csvParse). If those parse methods fail, or provided text data contains no location data we can extract, we display text output in a custom scrollable text container with [`code pre-wrap`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/code) for a quick copy/paste to other places. Otherwise, loaded data is converted to `GeoJSON` with our [`GeoConverter`](https://github.com/RandomFractals/vscode-leaflet/blob/main/src/renderer/geoConverter.ts) for locations display on the map. |
-| `application/xml` or `text/xml` | `XML` data with root node children that contain attributes ending with: `latitude`/`longitude`, `lat/lng`, or `lan/lng` | `XML` data support is experimental and might be removed later. |

See our [leafletMap.js](https://github.com/RandomFractals/vscode-leaflet/blob/main/src/renderer/leafletMap.js) for more info about that setup. |
