We have four SVG diagrams embedded in this page. Each is within a cyan-coloured div. The first 3 have a native size of 400x200, thus consume a height of 200 pixels on the page. The last is 300x60.
Test of resizing: the ones below are sized 50%, 100%, 150%. We did this by explicitly setting
the width and height in the embed tag.
Test of resizing again: the ones below are sized 50%, 100%, 150% by setting width only.
