This is not possible. I know that is not answer you would like but that is the reality. Workbooks are meant to be shared only within the Tenant. Any external user that needs access will require to be added to the Tenant as guest user. Additionally any user that views the workbook not only needs access to the workbook itself but to any data that the workbook uses. For example, if the workbook uses Log Analytics to query data the user needs to have access to the data that is queries. If the user does not have that access the workbook will either fail to visualize or not visualize anything. The same situation is if you export the workbook and it is imported into another tenant. If the workbook is made dynamically - it does not tie to any specific resource in your tenant it will also work when imported on other tenants as long as they have similar data. You best option is to use some other platform that has such kind of feature or to build your own custom web application that pulls the same data and visualize it. Of course always be careful with visualizing any sensitive data publicly.
