# The Mathematics of Infographics

### Introduction

I love infographics and there are some brilliant people making these at the moment. They are fraught with mathematical danger though and interpreting them and creating them depend on strong mathematical awareness and as such they provide opportunities for rich activity in areas of maths that go past statistics like, area and proportion for example. In this session the aim to show a number of examples that, as a group, we would analyse critically and then look at some examples of how these can be created perhaps from some of the data collected in the session ‘Data, Data, everywhere’. All with a view to concrete ideas for lessons.

### The Billion Dollargram

We will start with a puzzle based on the famous 'Billion Dollargram' image from information is beautiful.

### Presenting

Here we will look at some examples of infographics and some sources of infographics

A day in the life of the internet

Visual.ly - Infographics source

### Doing

Consider these infographics....

For each of the infographics above consider the questions below and each one comes with a series of questions about the mathematics behind them.

- How well is the information presenetd
- What questions does it make you want to ask
- Are there any errors
- Suggestions for motive?
- Suggestions for improvement?

### Creating infographics

Here we will look at some examples of how we might create infographics.

Olympic Circles - How do I decide the size of my circle?

### More Doing -

Creating a billiondollargram type exercise. Can you always use a rectangle

### Collaboration

When are there more opportunitites for us to create infographics how could we do it?

### Finish

Need to finish with something cool! - The probability you exist!
