+Overview
+--------
+
+VulnerableCode imports vulnerability advisories from dozens of data sources and
+grows its database continuously. However, it previously lacked a way to
+demonstrate its quality. This project enables VulnerableCode to visually
+showcase its data richness and coverage, while highlighting areas for improvement. This transparency
+gives users confidence in VulnerableCode and provides maintainers with actionable
+insights to improve it.

+This GSoC project builds three key features:
+
+* `Insights Dashboard`_: A multi-panel dashboard containing various interactive
+  charts to showcase VulnerableCode's strengths and identify areas for improvement.
+* `History of Advisories`_: A diff view for tracking changes in an advisory and
+  viewing its historical versions as snapshots.
+* `EPSS History`_: Visual tracking of EPSS score and percentile trends over time.

+Detailed Report

+
+Insights Dashboard
+^^^^^^^^^^^^^^^^^^
+
+The Insights Dashboard is a multi-panel interactive dashboard designed to
+visualize various features of VulnerableCode through infographic charts.
+
+A dedicated ``insights`` Django app houses the dashboard's core functionality.
+To ensure fast and scalable chart rendering, an automated daily snapshot pipeline
+(``insights_snapshot_pipeline.py``) pre-computes database-wide metrics once every night, avoiding
+heavy on the fly queries across VulnerableCode's million-row tables. These metrics
+are stored in dedicated models linked to a ``DailySnapshot``, keeping the telemetry
+structured and instantly queryable.
+
+Below is the tree view of ``insights`` for better understanding ::
+
+    insights
+     ├── models.py
+     ├── views.py
+     ├── urls.py
+     ├── utils.py

+     └── static/insights/
+           ├── css/insights.css
+           └── js/
+
+
+The dashboard panels are implemented using a modular framework in the ``charts/``
+directory. Each chart is driven by a ``ChartDefinition`` dataclass, which encapsulates
+all the metadata, collection, and formatting logic required to render it. These
+definitions are centrally registered in the ``insights/charts/__init__.py`` chart registry.
+At request time, the API simply fetches the latest pre-computed snapshot using these
+definitions, ensuring instantaneous page loads.
+
+The UI integrates Billboard.js to render interactive charts.

+
+History of Advisories
+^^^^^^^^^^^^^^^^^^^^^
+
+Advisory data imported from upstream sources is constantly updated. Previously,
+VulnerableCode only exposed the latest version of an advisory, making
+it impossible for users to track what changed over time.
+
+This feature introduces a chronological list of advisory versions, allowing users
+to click into any historical snapshot and view the advisory exactly as it
+existed at that moment. To provide a quick overview, the UI displays diffs between
+versions directly.
+
+These diffs are generated at import time. For existing advisories,
+they can also be backfilled using the ``HistoryDiffImproverPipeline``. The diffs
+are stored in the ``AdvisoryHistoryDiff`` model.

+
+
+
+
+EPSS History
+^^^^^^^^^^^^
+
+This feature adds an EPSS History Trend on the advisory page in the form of a line chart
+and a paginated history table showing the percentile and score of EPSS over time
+for a given advisory.

+
+The Insights Dashboard can be extended further with additional charts and panels to provide even
+richer data analytics and visibility. These insights act as a direct feedback loop, helping us
+continuously refine VulnerableCode by guiding the development of new data pipelines,
+targeted improvers, and architectural enhancements.
+
+
+Closing Thoughts
+----------------
+
+Working on VulnerableCode Insights was a truly rewarding experience that I thoroughly enjoyed.
+Designing the Insights Dashboard was a particularly thought-intensive process where
+I found myself drawing inspiration from various insights features like Spotify Capsule
+and GitHub Insights.
+
+The most amazing part of this journey was the `weekly meetings <https://meet.jit.si/AboutCode>`_ with my mentors. It was an
+incredibly smooth experience, and I owe a huge thanks to them for all their
+thoughtful inputs, guidance and feedback:
+
+Mentors: `Philippe Ombredanne <https://github.com/pombredanne>`_, `Hritik Vijay <https://github.com/hritik14>`_, `Keshav Priyadarshi <https://github.com/keshav-space>`_, `Ziad Hany <https://github.com/ziadhany>`_, `Ayan Sinha Mahapatra <https://github.com/AyanSinhaMahapatra>`_, and `Tushar Goel <https://github.com/TG1999>`_
+
+It was truly amazing to have this opportunity to learn, contribute, and grow with `AboutCode <https://github.com/aboutcode-org>`_ this summer, filled with tons of bugs and caffeine.
+
+Until next time!
