yes
I saw them but I want to avoid advertise and put clear chart
I found these guys
https://luxstack.com/widgets but have no Idea with this code in wp. When I put code in post I see only white space
Do you want it on the sidebar, or in a post?
If it's the former, create a new text widget and paste the HTML code it. If it's the latter, when you're making a new post, change the editor to the HTML tab and paste it in, then preview/publish.
Let me know if you need any help. That should work.
