Hi Abel

Thanks for reaching out in the Lucidchart Community! We're always looking for ways to improve Lucidchart and your feedback is the best way for us to do that. Would you mind adding your idea to our Product Feedback section to ensure it is given consideration on our product roadmap?  Ideas submitted are passed on to the product development team for their consideration. Let me know if you have any questions!

Did this ever happen? I really need the ability to produce this kind of chart?

Hi Nick

Thanks for posting in the community. We don't have a shape library or template intended specifically for causal loop diagrams so you may need to get creative with pieces of it but you should be able to build something similar by styling our standard shape library and designing/uploading a couple of custom shapes. If you'd like to see some templates or shape libraries specifically for causal loop diagrams please add the idea (and your use case for it!) to the feature request form linked above. Thanks!
