GraphVizDataFrame

Quickly generate a graph from a DataFrame.

Use the template.csv in examples as template or rename the columns of your dataframe accordingly.

using GraphVizDataFrame
using CSV, DataFrames
df1 = CSV.read("examples/01_departments.csv", DataFrame)
plot_dot(df1, "/tmp/dept.png")

Installation

Not yet registered, so install from github and track main branch:

using Pkg
pkg"add https://github.com/tp2750/GraphVizDataFrame.jl#main"

GraphViz

Make sure that edge_label is a string. It currently fails if they are all integers.

Edge_type

The column edge_type can be the following as described here: https://graphviz.org/docs/attr-types/style/

• "dashed"
• "dotted"
• "solid"
• "invis"
• "bold"
• "tapered"

Fillcolor

The nodex_fillcolor can be hex RGB, HSV or x11 strings, ad described here: https://graphviz.org/docs/attr-types/color/

Examples:

Color	RGB	HSV	String
White	"#ffffff"	"0.000 0.000 1.000"	"white"
Black	"#000000"	"0.000 0.000 0.000"	"black"
Red	"#ff0000"	"0.000 1.000 1.000"	"red"
Turquoise	"#40e0d0"	"0.482 0.714 0.878"	"turquoise"
Sienna	"#a0522d"	"0.051 0.718 0.627"	"sienna"

It will always be the last specified color that applies, node2_fillcolor is applied after node1_fillcolor

The x11 colors are listed here: https://en.wikipedia.org/wiki/X11_color_names
