Ethereum Graph Viewer is a D3.js-based web application that visualizes Ethereum transaction relationships. It allows users to enter an Ethereum address and view a graph representing the transaction interactions with the given address up to a specified depth level.

• Ethereum Address Input: Users can input any valid Ethereum address.
• Graph Depth Selection: Users can select the depth of the graph (1 to 3) to control the granularity of the visualization.
• Interactive Graph: The rendered graph is interactive, allowing users to zoom in/out and click on nodes for more information.

To set up the Ethereum Graph Viewer on your local machine, follow these steps:

1. Clone the Repository

   git clone [repository URL]
   cd ethereum-graph-viewer

2. Install Dependencies

   npm run build
   

3. Environment Variables

   • Create a .env file in the root directory.
   • Add the following line (replace <YOUR_ETHERSCAN_API_KEY> with your actual Etherscan API key):

     ETHERSCAN_API_KEY=<YOUR_ETHERSCAN_API_KEY>
     

4. Start the Application

   npm run start

Once the application is running:

1. Navigate to http://localhost:3000 (or the configured port).
2. Enter an Ethereum address in the input box.
3. Select the desired graph depth.
4. Click on "Show Graph" to visualize the Ethereum address interactions.
