Try it out: shawntabrizi.com/ethgraph
- Enter an Ethereum address (or use the default)
- Optionally set a start/end block range
- Click "Graph Balance" to plot the balance history

Uses ethers.js to query historical balances from a public RPC endpoint and Plotly.js for interactive charts. The Etherscan API finds the first transaction block for an address.
The URL updates with querystring parameters as you use the app, making it easy to share a specific view:
