In this chapter we will cover:
- Interacting with the mouse
- Interacting with a multi-touch device
- Implementing zoom and pan behavior
- Implementing the drag behavior
The ultimate goal of visualization design is to optimize applications so that they help us perform cognitive work more efficiently.
Ware C. (2012)
The goal of data visualization is to help the audience gain information from a large quantity of raw data quickly and efficiently through metaphor, mental model alignment, and cognitive magnification. So far in this book we have introduced various techniques to leverage D3 library implementing many types of visualization. However, we haven't touched a crucial aspect of visualization: human interaction. Various researches have concluded the unique value of human interaction in information visualization.
Visualization combined with computational steering allows faster analyses of more sophisticated scenarios...This case study adequately demonstrate that the interaction of a complex model with steering and interactive visualization can extend the applicability of the modelling beyond research
Barrass I. & Leng J (2011)
In this chapter we will focus on D3 human visualization interaction support, or as mentioned earlier learn how to add computational steering capability to your visualization.
