A '''sparge plot''' is a diagram depicting the unfettered positions of raw numerical data for several comparable univariate distributions in the context of non-parametric summary statistic scaffolding (e.g. quartiles) that indicate the quantitative dispersion and skew of the underlying points. This is technically accomplished using a combination of a) vertical stacking of the distributions of b) orthogonally jittered and c) translucent [overlapping] points while also d) subtly superimposing boxplots around the central assemblage of these points.<ref>{{Cite journal |last=Schruth |first=David |display-authors=et.al. |date=2024-01-05 |title=The origins of musicicality in the motion of primates |url=https://onlinelibrary.wiley.com/doi/abs/10.1002/ajpa.24891|journal=American Journal of Biological Anthropology |volume=184 |issue=1 |pages=e24891 |doi=10.1002/ajpa.24891 |pmid=38180286 |language=en }}</ref><ref>{{Cite journal |last=Schruth |first=David |date=2023-11-09 |title=Plot Sparge: Visually compare all points from different univariate distributions |url=https://search.r-project.org/CRAN/refmans/caroline/html/plot.sparge.html |journal=Comprehensive R Archive Network |language=en }}</ref>

Sparge plots are similar to [[sina plot]]s or [[raincloud plot]]s in that they are largely empowered by the datapoints themselves. However, in contrast to sina and raincloud plots, which typically emphasize a simplification of data distribution using kernel density, sparge plots merely overlay a more subtle boxplot to quantitatively demarcate such dispersion. 

An easy way to create a sparge plot is by using the 'plot.sparge' function in the 'caroline' R-package:
