MLSToolbox Code Generator main page is divided into three panels:

• Menu panel (on the left), this panel appears and hides clicking on buttons >> and << respectively at the top of the left panel. This panel contains the following options:
  • File menu includes the options to create a model from scratch or using a template, load and save pipeline, and generate pipeline code.
  • Model Explorer allows to visualise the pipeline in a hierarchical way, similar to how a file system displays folders and subfolders in a directory tree. The user can navigate though the model explorer, and the selected element on the model explorer will be shown on the Canvas. The previous figure shows the Model Explorer view on the left panel.
• General Editor (in the middle). This is the edition area where the user can define the ML pipeline with its stages and tasks (as boxes/nodes), the data flow through stages, inputs (at the left of the boxes) and outputs (on the right of the boxes).
• Details panel (on the right). When one box/node is selected on the edition area, this panel provides the details related to the selected element and some actions (edit, delete).

At the bottom of the General Editor there are some buttons to arrange the boxes/nodes displayed.
