I like the fact that it is interactive and easy to use. I think it is a great tool for the visualization of large data sets. The only thing I dislike is the lack of documentation. There is not a lot of information about how to use the tool. So if you are not familiar with the tool it can be difficult to use. We are using it to create graphs for our customers. This is a great tool for large data sets. We are able to create interactive graphs that our customers can use to understand and visualize their data.
