Description

As part of my collaborative Master's Thesis (TFM), I have developed two new features for TimeOverflow that complement those already presented in PRs #790, #791, #792, and #796:

1. Geospatial visualization: Implementation of tools for visualizing geographic data related to time banks and their users, allowing a better understanding of the spatial distribution of the community and optimizing the search for services by proximity.

2. Statistical analysis: Development of functionalities to generate statistical reports and data visualizations about time bank activity, including participation metrics, most frequent exchanges, and temporal trends.

Proposal

I am willing to prepare a separate PR for each of these new features if the maintenance team is interested in integrating them into the main project.

I look forward to your feedback on whether these features are of interest to the project.
