The arrows.meta tikz library allows you to change the style of an arrowhead. I think -{Latex[length=2mm]} looks nice for my figures.
However, I don't want to type "-{Latex[length=2mm]}" every time I draw an edge. How can I make this style the default for all arrows in the figure, so that I get this style of arrow head every time I write ->?
\tikzset{>={Latex[length=2mm]}}. (after importing tikz and arrows.meta of course.) – N. Virgo Aug 10 '20 at 07:57
