  - Let's update the size of our svg (this will be enclosed in a viewbox, inside the viewBox we will play with exact coordinates, outside with percentages)
  ```diff
  - const svgDimensions = { width: 800, height: 500 };
  -+ const svgDimensions = { width: 500, height: 250 };
  ++ const svgDimensions = { width: 500, height: 500 };
  ```
  - Let's enclose the **svg** we are displaying in a **viewBox** (now sgv will have a _width_ and _height_ of 100%)
