because your data isn't going to analyze itself!
Reason is an interactive form of yt, totally accessible from a web browser. It has full yt capabilities, as if you are acting from the Python intepreter, yet it also provides a new way of interacting directly with your data objects. Because it is run through a web browser, you can run it remotely on HPC facilities where your data may reside, while manipulating and visualizing it in real time at your own local console.
The Reason layout consists of a yt input box as well as an output window. Whenever you press shift-enter, the contents of your input box is sent to the server and the results returned. While the server is processing, the box around the input form will turn red and become read-only. When the server has returned a result, it will return to normal and allow input.
When using the Reason window to create a plot collection object, the saved images will be returned in the window. You can click on these images to view them at full-size.
As you execute cells and load parameter files from disk, these parameter files will get added to the tree view on the left, along with any objects that have been created from them.
Over time, these objects will expose right-click events to create plot windows, as well as drag-and-drop functionality.
There are three methods for saving your work. You can click "Download" to download a copy of your session on your local machine. By clicking "Save" you can save a copy on the server on which Reason is running. By clicking "Pastebin" you can send a copy of it to the yt pastebin.
If you use the command 'load_script' and supply it a file the server can find locally, it will read that file in and populate the contents of your next submission cell with it.
To quit, simply press Ctrl-C in the console window that you ran "yt serve" within.
