Go Web Graph Application

This project is a web application that visualizes a directed graph of nodes with specific criteria. The application is built using Go for the backend and utilizes an SQLite database to store and retrieve graph data.

Setup Instructions

1. Clone the Repository

   git clone <repository-url>
   cd go-web-graph-app

2. Install Dependencies Ensure you have Go installed. Run the following command to download the necessary dependencies:

   go mod tidy

3. Set Up the Database

   • Create an SQLite database and run the SQL schema defined in internal/db/schema.sql to set up the required tables.

4. Run the Application Start the server by running:

   go run cmd/server/main.go

5. Access the Web Application Open your web browser and navigate to http://localhost:8080 to view the graph visualization.

Usage

The application retrieves nodes with an indegree greater than 5 and within the range of -100 to 100 on both axes. Users can interact with the graph by moving and zooming to explore the relationships between nodes.
