docs(wiki): create page explaining available chart types

[marcgc21]

Description

Create a Wiki page that documents all the different chart types used in the project. This page should explain what each chart represents, what data it uses, and how it supports project analysis. It will serve as a reference for contributors, analysts, and users of the system.

📚 Charts to Document

• Commits Over Time
• Top Contributors
• Code Frequency (Additions/Deletions)
• Pull Request Activity
• Issue Activity
• Contributor Activity Heatmap
• Repository Growth Over Time
• (Optional) Any custom or experimental charts

---

✅ Tasks

• Create a new Wiki page (e.g., Chart Overview)
• For each chart:
  • Add title and purpose
  • Include a sample image or placeholder
  • Describe data source and fields used
  • Explain how to interpret the chart
• Link the page from the main Wiki index (if exists)
• (Optional) Add versioning notes if charts evolve over time

---

✅ Acceptance Criteria

• All major chart types are documented clearly
• Each section includes chart purpose, data source, and example
• Page is accessible via the repository Wiki
• Information is beginner-friendly and easy to update

I would like to take on this documentation task. I've reviewed the requirements and have a clear plan to create a structured Wiki page......

For each chart type, I will create a section that includes its purpose, the data it uses, an example image, and a simple explanation of how to interpret it.

I am ready to begin. Please assign this issue to me.

@marcgc21 i would like to work on this issue
here’s how I plan to approach it:
• First, I’ll review the existing charts used across the project (dashboards, analytics views, or documentation) to identify all current chart types, including any experimental ones.
• I’ll create a new Wiki page titled “Chart Overview” and structure it so each chart has its own clearly defined section.
• For every chart, I’ll document:
• The chart’s purpose and what insight it provides
• The data source and key fields used (e.g., commits, PRs, issues, contributors)
• How to interpret the chart, written in a beginner-friendly way
• A sample image or placeholder (with scope to update later)
• I’ll ensure the content is easy to maintain and update if charts evolve, optionally adding brief versioning notes where relevant.
• Finally, I’ll link this page from the main Wiki index so it’s easily discoverable for contributors and analysts.

Please let me know if this approach aligns with your expectations or if there are specific charts or repositories you’d like me to prioritize. Thanks!
