Describe three challenges data visualization researchers face when trying to build an interface. Suggest solutions to conquer these problems.

What will be an ideal response?

The challenges are:
Importing and cleaning data
Integrating data mining
Viewing big data
Achieving universal usability
Supporting casual users
Dissemination and storytelling
Adapting to any device
Evaluation

Some of the solutions include, respectively, getting data into the correct formats, using Screen Tips and labels, using dynamic visualization to show millions of items, use statistical techniques to find patterns in data mining, add analytical reasoning tools to visualization, user-defined captions to assist in identification and collaboration, and making visualization tools usable by all users.
