Data Visualization

Part 1

Andy Kirk, of Visualising data,  believes that data visualisation is a mixture of art and science,  creativity, analysis and project management. He sees 8 “hats” in the  data visualisation process, which can either be worn by different  members of a team, or can be deliberate mindsets adopted by a solo  professional.  Understanding how each contributes to the finished  product is perhaps the key to creating great data visualisation designs…
Think  about the role you played in creating a presentation or working on a  project using data visualizations. Choose two of the 8 hats and explain  your roles (in relation to these hats) in creating the presentation or  finishing the project.
