I noticed that [Plotly is integrated with Mapbox-gl](https://plotly.com/python/mapbox-layers/), and the [Mapbox-GL support different projections](https://docs.mapbox.com/mapbox-gl-js/guides/projections/), so it should be easy to have this option in Plotly. It looks like it's already supported in `scatter_geo` (see the [doc](https://plotly.com/python-api-reference/generated/plotly.express.scatter_geo.html))but not Mapbox layers.\r\n\r\nSee projections support in Mapbox-GL [here](https://docs.mapbox.com/mapbox-gl-js/guides/projections/). See what's looks like with projection here,\r\n\u003cimg width=\"681\" alt=\"image\" src=\"https://user-images.githubusercontent.com/5254627/236315193-3090e555-630b-4a50-89e0-806d0d93dca0.png\"\u003e\r\n\u003cimg width=\"682\" alt=\"image\" src=\"https://user-images.githubusercontent.com/5254627/236315273-e46555ff-4a7b-4f62-9c4d-17597e7fc26e.png\"\u003e\r\n\r\nThe code by the support the function should look like,\r\n\r\n```python\r\nimport pandas as pd\r\nus_cities = pd.read_csv(\"https://raw.githubusercontent.com/plotly/datasets/master/us-cities-top-1k.csv\")\r\n\r\nimport plotly.express as px\r\n\r\nfig = px.scatter_mapbox(us_cities, lat=\"lat\", lon=\"lon\", hover_name=\"City\", hover_data=[\"State\", \"Population\"],\r\n                        color_discrete_sequence=[\"fuchsia\"], zoom=3, height=300)\r\nfig.update_layout(\r\n    mapbox_style=\"white-bg\",\r\n    mapbox_layers=[\r\n        {\r\n            \"below\": 'traces',\r\n            \"sourcetype\": \"raster\",\r\n            \"sourceattribution\": \"United States Geological Survey\",\r\n            \"source\": [\r\n                \"https://basemap.nationalmap.gov/arcgis/rest/services/USGSImageryOnly/MapServer/tile/{z}/{y}/{x}\"\r\n            ]\r\n        }\r\n      ])\r\nfig.update_layout(margin={\"r\":0,\"t\":0,\"l\":0,\"b\":0}, projection= 'globe')\r\nfig.show()\r\n```\r\nthe `projection` option can be configured to support more projections\r\n ","author":{"url":"https://github.com/wybert","@type":"Person","name":"wybert"},"datePublished":"2023-05-04T20:04:06.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/4189/plotly.py/issues/4189"}
