There are certain questions, answer of which require a graph, diagram or animation of locus or more precisely something related to Geogebra.
So, is asking input command of how to make any animation for e.g. "How to make cardioid animation in Geogebra" considered on-topic?
Stack Overflow has a Geogebra tag but I noticed that the question there are simply ignored (this is not the only reason). I thought that Geogebra has wide use in Math SE, too, so why not ask question here itself. It may also help other users to get familiar with Geogebra interface which in turn would enhance the quality of answer by using it.
