d2.data.frame: Generate D2 input text to plot a data frame

In autodb: Automatic Database Normalisation for Data Frames

Generate D2 input text to plot a data frame

Description

Produces text input for D2 to make a diagram of a given data frame, usually rendered with SVG.

Usage

## S3 method for class 'data.frame'
d2(x, name = NA_character_, nest_level = Inf, ...)

Arguments

x	a data.frame.
name	a character scalar, giving the name of the record, if any. The name must be non-empty, since it is also used to name the single table in the plot. Defaults to NA: if left missing, it is set to "data".
nest_level	an integer, giving the amount of nesting allowed when giving the class of a list column. Since lists can hold anything in R, this allows showing common element classes and lengths.
...	further arguments passed to or from other methods.

Details

The rows in the plotted data frame include information about the attribute classes.

Value

A scalar character, containing text input for Graphviz.
