Visualizations to explain the results of a topological
data analysis. The goal of topological data analysis is to identify
persistent topological structures, such as loops (topological circles)
and voids (topological spheres), in data sets. The output of an
analysis using the 'TDA' package is a Rips diagram (named after the
mathematician Eliyahu Rips). The goal of 'RPointCloud' is to fill in
these holes in the data by providing tools to visualize the features
that help explain the structures found in the Rips diagram. See McGee
and colleagues (2024)
