# Bivariate data

### From WikiViz

We have bivariate data when two dependent variables varying against an independent one.

Bivariate linear data are easily representable as a single image which relates data values with some scale in a plain. Conventional approaches are Graphs such as Line graph, Histograms, and Scatterplot

When used with bivariate data, scatterplots are helpful for encouraging the viewer to assess the possible causal relationship between the two plotted variables

Histograms are suitable to facilitate comparisons between the values of a dimension, while scatterplots are helpful to convey overall impression of relationships between two variables.
