A canvas name is a file name. The output name is to be shown on your web report.
In the home view, you will see the canvas name on the right, compared to the output name, next to it.
When you create a new canvas, you will have the chance to name the respective canvas. Think of the canvas name as a file name. The canvas name will not be the name displayed on your web report, once it is public.
You can easily change the output name in the last node and canvas of your supply chain – most likely a storage box. The output name is the one to be shown on your web report.
That is why we usually recommend to use your brand name and official product name.
