3D London maps, overlaid with air quality data
- Use of 3D for presenting data can obscure values, for example where low-value data points lie behind high-value points. Allowing the user to interact with the visualisation, eg rotating or moving the view, can get round this issue.
- Animations can be created in a range of standard data applications such as Excel, with the output saved for each different time-point, and an image editor or language such as Adobe Flash used to splice them into an animation. Online tools include Google Motion Charts.
