# Setup Instructions
Since we are not using a package manager, you need to manually download the Chart.js library.
1. **Download Chart.js**
- Click this link: [Chart.js UMD Build](https://cdn.jsdelivr.net/npm/chart.js@4.4.1/dist/chart.umd.min.js)
- Right-click the page/code and select "Save Page As..." (or "Save As...").
- Save the file as `chart.js` inside the `lib` folder of your project.
- **Path**: `e:\dev\antigrav_lab\lib\chart.js`
2. **Verify**
- Ensure the file exists at `lib\chart.js`.
3. **Run**
- Open `index.html` in your browser.
