States will adjust in size relative to the width of the container div, which allows SVG elements to be appropriately sized regardless of device size or screen resolution, making it a good way to integrate D3 and Bootstrap.
Click “Open in a new window”, change the size of your browser window, and the states will scale with it. *Will not work in the standard bl.ocks.org view
Please let me know if there is a better/native way to do this!
