Thanks for the PR.

Some comments

1. The example spatial queries need to be carefully crafted. This is the one we currently use on Sedona main page and I suggest we still use it. This is a classical Spatial SQL example from PostGIS.

SELECT superhero.name
FROM city, superhero
WHERE ST_Contains(city.geom, superhero.geom)
AND city.name = 'Gotham'

Please prepare the same example for (1) SedonaSpark (2) SedonaDB. Don't do any Java example or irrelevant PySpark example.

2. Please do not use Sedona Snowflake in any coding example or deployment as it is impossible to run them locally.

I suggest the following deployment mode

SedonaSpark

pip install apache-sedona

SedonaSpark in Docker

docker pull apache/sedona:latest
docker run -d -p 8888:8888 -p 8085:8085 apache/sedona:latest

SedonaDB

pip install apache-sedona[db]

Please don't use absolute paths, use relative path instead.

I believe it will look like "setup/overview/". Please try locally.

Same here. There are a few other places as well.
