**AltGraph is a set of reference applications that demonstrate how to build “graph applications” with Cosmos DB for NoSQL and leverage its’ features to achieve a performant, integrated, and low-cost solutions. It currently demonstrates two different graph use-cases, with two different implementations.**

Currently, AltGraph is built with the **Java** programming language, and
the **Spring Boot** and **Spring Data** frameworks. **D3.js** is used in
the Web UI for visualizations, but you can use any similar JavaScript library
for your implementations. There is also an implementation in C# in the `dotnet` directory.

At this time, **there are two designs and implementations for your reference**:

- A **version 1** design uses the concept of "RDF Triples" to implement a **Bill-of-Materials**
  graph using **NPM** data (the Node Package Manager tool in the Node.js ecosystem).
  The graph of dependencies for a library can be seen as a bill-of-materials.

- A **version 2** design featuring more in-memory functionality and the **JGraphT**
  software library. This implementation used the **IMDb** (Internet Movie Database)
  dataset as a very rich social-network. The large downloadable IMDb datasets
  encourage the exploration of "the six degrees of Kevin Bacon".
  The wrangled AltGraph IMDb data contains over **1-million vertices and 3.9 million edges**,
  all stored in-memory in the JVM (Java Virtual Machine) with JGraphT.

These implementations may be used as-is, or as a starting point for your own implementations. Both are designed to showcase the power and efficiency of the
**Cosmos DB NoSQL API** for graph solutions.
