%description
An HTML widget that randomly tours 2D projections of numerical data. A
random walk through projections of the data is shown. The user can
manipulate the plot to use specified axes, or turn on Guided Tour mode to
find an informative projection of the data. Groups within the data can be
hidden or shown, as can particular axes. Points can be brushed, and the
selection can be linked to other widgets using crosstalk. The underlying
method to produce the random walk and projection pursuit uses Langevin
dynamics. The widget can be used from within R, or included in a
self-contained R Markdown or Quarto document or presentation, or used in a
Shiny app.
