A correlogram or correlation matrix allows to analyse the relationship between each pair of numeric variables of a dataset. This kind of chart is more used for exploratory purpose than explanatory (read more). Thus, its implementation in d3 is quite rare.

Step by step

In a correlogram, the relationship between each pair of variable is visualised through a scatterplot, or a symbol that represents the correlation (bubble, line, number..). The diagonal often represents the distribution of each variable, using an histogram or a density plot.

Selection of blocks

Not many blocks are available for correlogram. It makes sense, since correlogram are more used for exploratory analysis than for explanatory purposes (read more). Thus, they are not often build using d3.js
