It is possible to see an overall view of your saved visuals from both the Dashboard and also in the Editor while you are creating. :)
Upon login, you will be in the Dashboard. The visuals shown here are your currently saved Piktocharts. Hover over your saved visual design. From there, simply click "Preview".
In preview mode, you can view your saved visuals without the distractions of the editor. It provides a clear picture of what your visual will look like when embedded or printed out.
2. While you're creating in the Piktochart editor, click the teal Preview button in between the Save button and Download button. The most accurate Preview is available when you've clicked the Save button before exiting the editor.
