 ## Notes
 
+- At first [I tried to do it with JSDOM](https://github.com/stereobooster/venn-nodejs). It doesn't
+  work, because it needs `getComputedTextLength` for layout.
 - Algorithm is not stable, so tests doesn't work (svg output everytime is different)
 - Not exposed: `wrap`, `useViewBox`, `width`, `height`, `padding`, `colours`, `colors`, `fontSize`,
   `normalize`, `layoutFunction`, `scaleToFit`, `styled`, `round`, `distinct`, `orientation`,
