The grid is already created through a series of XLINKs, which is rather compact coding. The original file (before text was converted into paths) was 5kb in filesize, but I couldn't upload that version due to vagaries and inconsistencies in RSVG font rendering (see file upload history of File:Simple inverse relationship chart.svg) and lost it in a hard disk crash about 7 years back.
Unfortunately, your "optimization" of the SVG consists of glomming all the text paths together into one huge path, using relative coordinates, and throwing away all positioning information beyond the first decimal digit of accuracy. I really do not find these changes to be any kind of desirable or useful "optimization"... AnonMoos (talk) 18:17, 3 August 2016 (UTC)
- There's a file-specific discussion area at File_talk:Half-age-plus-seven-relationship-rule.svg, but such pages are often not used when only two users are involved in a discussion. I've never used patterns in any of the SVG files that I've created from scratch, and they're often a pain when debugging files created by Inkscape etc. I don't think they would give any great advantage in this file. It's true that some earlier versions of Inkscape generated spurious extra decimal digits of useless precision, but File:Half-age-plus-seven-relationship-rule.svg was not generated by Inkscape, and doesn't have that problem. If you have a radical new extreme philosophy of SVG design, then on the whole I would prefer that you test it out on your own files. AnonMoos (talk) 03:48, 9 August 2016 (UTC)
