Hi,

I did test and got the same results using https://fordi.org/shaper-dots.svg. I looked at the web page source, and can see that the recent changes you made, is not reflected in https://fordi.org/shaper-dots.svg. Could you eventually setup a "https://fordi.org/TESTING-shaper-dots.svg" webpage?

I'd rather not put testing in prod. Can you just download the SVG file and drag it to your browser?

Nevermind. I've updated the gist's SVG and JSX to match what heusserurs is doing, and updated https://fordi.org/shaper-dots.svg

THX :)
