+
+_Make some beautiful corner plots._
+
+```{admonition} Corner plot /ˈkôrnər plät/ (noun):
+:class: tip
+
+An illustrative representation of different projections of samples in
+high dimensional spaces. It is awesome. I promise.
+_Synonyms: scatterplot matrix, pairs plot, draftsman's display_
+```
+
+This Python module uses [matplotlib](https://matplotlib.org/) to visualize
+multidimensional samples using a scatterplot matrix.
+In these visualizations, each one- and two-dimensional projection of the
+sample is plotted to reveal covariances.
+_corner_ was originally conceived to display the results of Markov Chain
+Monte Carlo simulations and the defaults are chosen with this application in
+mind but it can be used for displaying many qualitatively different samples.
+
+Development of _corner_ happens [on GitHub](https://github.com/dfm/corner.py) so you can [raise any issues you have there](https://github.com/dfm/corner.py/issues).
+_corner_ has been used extensively in the astronomical literature and it [has occasionally been cited](https://ui.adsabs.harvard.edu/abs/2016JOSS....1...24F/citations)
+as `corner.py` or using its previous name `triangle.py`.
