Re: [O] [babel] create tikz pictures in an floating LaTeX environment

[Darlan Cavalcante Moreira]

I have a (very) small personal wiki in org mode where I add stuff that I
read/learn that deserve this work. I usually don't need to export it, but
recently I was trying to export it to PDF and HTML and I had the same doubt
with a block o tikz code.

It would be nice if org had a begin_tikz block. This block could either
create a PDF file or include the tikz code directly in the latex file when
exporting to latex (or PDF), and create an SVG file when when exporting to
HTML. Of course this block should accept all the usual image options, such
as caption and width.

This is just a feature request from a tikz lover.
