Trying to figure out how to best add text to an SVG, I thought maybe it doesn't show up because it's black-on-black, so I gave it stroke="white" before realizing I need to zoom out. Well, and stroke means the outline in SVG, so on the white background, it just makes the font look really thin.

This is the whole code:

<svg viewBox="0 -5 40 10" xmlns="http://www.w3.org/2000/svg">
  <text stroke="white">hello</text>
  <circle id="myCircle" cx="5" cy="5" r="4" />
  <use href="#myCircle" x="10" fill="blue" />
  <use href="#myCircle" x="20" fill="white" stroke="red" />
</svg>

And most of that is just this MDN example: https://developer.mozilla.org/en-US/docs/Web/SVG/Reference/Element/use#example

It does use my default font, which is Fira Sans. Will look different on other systems.
