This PR aims to create a somewhat better user experience when
interacting with the SVG.

## Implementation 
Previously, the SVG container should have updated its size whenever the
user resized the window. This did not work as expected and led to some
jankiness.

I removed the SVG resizing, because it led to the zoom level resetting
every time you resized the window. Now, the SVG expands to fill the
available space on mount, and then you change the size by zooming in and
out.

The toolbar is also removed, but I kept the "minimap" for now.
