Because I'm keeping track of how much I spent in the matter of three months I think analytical processes would be one good idea to use for my infographic. My two participants would be total spent (the whole) and the parts would be all the spending in different areas.
I could also do dimensional and quantitative topography as an infographic. Pie charts are an example of this.
Charts are drawn to scale. How much I spend totaling it all up is obvious and it would be interesting to see it all put together on one chart.
