The lecture started with the reason why we use graphs is to make comparisons easier. Often times graphic designers choose ineffective ways of displaying data due to aesthetic purposes.
An example of this was the use of “bubble charts”. A graphic is shown from Alberto Cairo’s book, The Functional Art.
It is shown that readers can easily calculate and lengths and widths, but cannot do so calculating surface area, specifically of a circle.
The following graphic shows different approaches to visualise and compare data:
This lecture pod showed us the different types of graphs and which are most effective for interpreting data. This is important for when we create our own graphs so we are mindful in presenting data in a way that is easily understood, while also presenting data accurately.
