This lecture pod was about why we use data visualisations at all and its various used throughout our history. This lecture showed various historical uses of data visualisation like the visualisation of Napoleon’s invasion of Moscow, Florence Nightingales charts of causes for death among British soldiers, Otto Neurath’s , and serialised charts all the way to the recent work by Alberto Cairo, The Functional Art.

Numerous key points made in this lecture which all related to the historical examples given. The first was the visualisation is used to an audience grasp complex ideas and difficult concepts quickly. Other points similar to this are made like extracting meaning from raw data is difficult, but a graphic makes it simple, saving us time and effort. Another point made is that a visualisations aim is for your eyes and you brain to perceive what lies beyond their natural reach. Another good point made in the lecture is that data visualisations are more complex today because we have access to much more data than ever before.

But I believe the most important point made in this lecture was really very simple, that what you show in a visualisation can be just as important as what you don’t. This point struck home for me because it made me realise that sometimes showing only a small amount of data can be more effective than showing all of it. But it also made me realise something else, just how easy it is to convince people of a statistic through the simple fact or omitting it from a visualisation.
