Axes labels overlapping when zoomed out

[AmberSJones]

When I zoom out on my browser to 90%, the axes labels redraw and overlap (see below). At 75%, the labels seem good.

I've made changes before to prevent this from happening, but it keeps coming back. Right now the spacing is handled by the d3.js library and there's not much I can do. I will keep investigating and update on the issue if I find something.
