text: Title: Gatherplot Feature Visualizer
  Body: Gatherplots could be a useful feature analysis tool for Yellowbrick, as they enable users to more easily visualize patterns in large datasets by stacking overlapping points.
  
  ### Proposal
  
  It would be interesting to implement a `GatherPlot` visualizer in the Yellowbrick API to address the problem of overplotting of data points when visualizing large datasets in a scatterplot. Instead of overlapping, data points that map to the same position are stacked together.
