Text without hyphenation with Tikz

Or don't specify the text width at all, just add a line break at the appropriate position.

\node[align=left] {Contemplando a\\contemporaneidade};

Increase the value for text width conveniently.

Instead of using align=left, you can use align=flush left. This seems to do exactly the same as align=left, but without the hyphenation.

\node[align=flush left,text width=3cm] {Contemplando a contemporaneidade};

I found this trick here: Manual/automatic line breaks and text alignment in TikZ nodes
