Title:

Fix tutorial: display custom maps code block (Issue #643)

Description:

This PR fixes the missing custom maps example in the tutorial (tutorial.rst).

Added a blank line after the .. ipython:: python directive to ensure the code block is correctly rendered in the Sphinx build.

Updated the tutorial to show how to create custom maps with markers, circles, and regions.

Verified that the HTML build now includes the custom maps code at the end of the tutorial.
