Review on tanzle by Rick Everett

The interface is very simple and intuitive to use. You can add various data sources (e.g. data from a csv file) and visualize them with different charts. It's free but I don't think you can save your visualizations. Furthermore, I'd like to have more options in changing colors of elements or shapes. It would be great if we could set up our own styles for the visualization. Visualization of data from csv files, which are used as reference data in our department. We also create models that can be used for the prediction of future values (in this case: what is the value of a product after 5 years).
