Add tensorflow (#892)

* fix(2003bc4): make W3C validator happier

Objection your Honor!
The offset attribute[^1] has an initial value and should not be required[^2];
but this (seems) to be SVG 2 and the W3C Validator goes up to SVG 1.1
(and the SVG 2 namespace is shared with the previous versions [^3]).

[^3]: https://www.w3.org/TR/SVG2/struct.html#Namespace

* Update README
