Having now selected my font (Phosphate) I gave my infographic a title. Something that is not technical and explicitly say what it is doing. The title ended up being. Meteorites: A map of terrestrial craters across the earth.
I think this title is good as it says exactly what I aim to show and is sort of evocative of graph naming in science.
I chose these fonts because it has that retro futuristic feel to it, but also kind of like a 1950s movie theatre sign which I think lends itself well to this poster as I have used some movie posters for inspiration. The second font used is raleway dots. However I think I may change this due to it not being very visible making the subtitle less significant.
