Hi @svrnm . It's done!

[chalin]

Thanks for the diagram, but the SVG isn't editable by our OSS contributors who don't have access to Adobe software, including myself.

That is, the SVG contains about 4000 lines of CDATA:

<metadata>
    <i:aipgfRef id="adobe_illustrator_pgf"/>
    <i:aipgf id="adobe_illustrator_pgf" i:pgfEncoding="zstd/base64" i:pgfVersion="24">

lx9PYc5cBDQEWgTywQy+upQHo/S1q8qGvuPrwfhTGkso/ToU9Nc3O7rGN4FfffNH4ASL0p8fRonA
... [for about 4000 more lines]

This isn't editable without use of proprietary software.

@leandrocaracciolo thanks, the CLA is the first step:-)

Re @chalin's question: the image you shared on slack is editable, this seems to be a different export, can you double check on that?

[leandro-caracciolo]

Hi @svrnm, thanks for the feedback! Yes, I've just pushed an updated version of the SVG (a5113854) that was re-exported using Inkscape (Plain SVG option). This should address the editability issue raised by @chalin and fix the prettier linting error. Please let me know if it looks better now.

[svrnm]

That looks great @leandro-caracciolo !

The last time I had a quick check, I noticed that there is still a 3-4K CDATA entry. Can the be removed? Do we know what it is?
