Heatmap with dendrogram

Dear Colleagues,

we are very exited using your library in our projects and thank you for developing it. Our team is quite eager to know whether you have plans to add a dendrogram and heatmap with dendrogram in the upcoming releases? If you don't have such plans and since we need these kind of plots very much, probably you may give us a guide how we can implement these plots, then we will be able to make a proper PR.

Warm regards,
Stanislav
