When quickly putting a draft presentation together, it is tempting to not spend any effort at all on design and layout. “We can always fix that later”.
I would argue the opposite. Make the draft look as good as the final product will be. It sets the entire mood for the project. Looking at messy / ugly charts is not a big motivation to do great work. Messy / ugly charts encourage people to add bullet point and too much text, because you can always remove it later.
The good news is that a simple chart with simple content does not take a lot of effort to design properly. Fix proportions, alignment and colors and everything looks great in a few clicks.
