Yes. Our tool pages every 500 bases: http://clab.ist.unomaha.edu/CLAB/index.php/RT386 click demo
what if you took a similar approach with your svg? each zoom level displays only what you need. new zoom requests (ajax) make a new query in the background.
A circular SVG render might be neat for a single top-level overview of landmarks in the million bases, but any zoom level being circular or graphical would add nothing useful to the GUI.
