Lecture 1 – Introduction

Visualization is a mass medium, for data visualization which is essential for communicating information and presentation of data.

Data is a measurement of values, either in quantity or qualitive, where it is displayed as graphs or images to create ‘Data Visualisation’ – it is the ‘modern equivalent’ of visual communication. It is information displayed as a schematic form including for units of information.

The aim of data visualisation is to display and communicate ‘graphics, plots or information graphics’

The difference between info graphics and data visualisation?

‘Not all information visualisations are based on data, but all data visualisations are information visualisations’

Some infographics are not based on data and are shown as a ‘description of a process’ The following is an example of an infographic showing just a list of steps and picture with no data involved.

The reason for data visualisation is to help users understand complex data, create stories, understand causes/effects and to make comparisons.

‘Processing – Analysing – Communicating – this data presents variety of ethical and analytical challenges for designers’ It’s important to have the right visualisation to the type of things you want to visualise.
