Graph Visualizer Telegram Bot

Project Description💡

This Telegram bot simplifies graph visualization for users, particularly in competitive programming contexts. It empowers users to seamlessly convert textual graph representations into clear and aesthetically pleasing visualizations.

Key Features⚙️

• Effortless Graph Input: Users submit a list of edges (and optional labels) representing their graph structure.
• Customizable Output: The bot generates an image of the graph, employing the Graphviz library to render the visuals.
• Directed/Undirected Support: Handles both directed and undirected graphs.
• Intuitive Interaction: Guides users through the visualization process with clear commands and prompts.

Install

1. Install Graphviz: Ensure Graphviz is installed on your system and PATH variable is set(https://graphviz.org/download/).
2. Clone repository from GitHub.
3. Set Environment Variables: Create a .env file in your project's root directory and add this line, replacing the placeholder with your bot token:

   TELOXIDE_TOKEN=YOUR_TOKEN
   RUST_LOG=LOG_LEVEL

4. Run the Bot: Execute the following command in your terminal:

   cargo run

How to use

1. Send a list of vertices in the following format:

   A B
   B C
   C D
   

   

   Each line represents an edge connecting two vertices. Vertices are separated by a space.

2. Optionally, you can add a third parameter as the label for the edge:

   A B Edge1
   B C Edge2
   C D Edge3
   

   

3. Also, you can add just nodes in a single line:

   A B
   C
   D
   

   

4. The bot will convert the graph into a PNG image and send it back to you.

5. Enjoy!
