I used the noun project for the backgrounds which i made transparent to go behind the main parts of the infographic to create depth. For this i used symbols that relate to the facts that i chose to include in my infographic.
I then added stars to create a space like effect.
The inspiration for the background of my infographic came from this one i found which is about space. I decided to use the space theme as Einstein wrote a lot about space and it ties all of the facts together. I chose a dark blue background as a black looked too serious and didnt fit my demographic (10-15)
This infographic also uses a flat style of graphics which i wanted to use with mine.
