I searched an archive and recommendation about Charts. I ticked a check box of "Show legacy simple charts" but it still doesn't work. Could you please suggest further action? Thanks.
Try this, in the same screen where you activated the legacy chart, a little further down you will find the box HTML5 Safe mode. Check it and try again.

Thanks a lot for your suggestion. The visualization is shown now. Thank you.
