Palladio

A "web-based app that allows you to upload, visualize, and filter your data on-the-fly. A Palladio project begins first with the tabular data you have on your computer. Once you’ve uploaded this data into the Palladio interface, you can then refine it, visualize, and save it back to your computer as a Palladio project. The Palladio project will be saved with the extension .json and includes the schema and structure required to visualize your data in Palladio the next time you visit. (In other words, you cannot simply upload any .json file created elsewhere and expect it to work within the Palladio platform.)" (Palladio).
