interactive visualization can help increase end-user interest in data exploration
If you have a look at what the designers at NY Times have created, you’ll be very impressed by the way the let you interact with the data. The used metaphor is very clear and it continuously incorporates new data. The available filters let you easily find a question that YOU are interested in, rather than the question(s) that the visual designers did want to answer. On the other hand, it is not so easily aware how many percent of the answers are in which area on the chart. Also, it is not clear how they decided which feeling would be “good”, “bad” or “neutral”. However, this kind of interactive visualization would be a very interesting type of awareness and exploration support for all stakeholders involved in Learning Analytics.
