Compose

Compose is a declarative vector graphics system written in Julia. It's designed to simplify the creation of complex graphics and serves as the basis of the Gadfly data visualization package.

Package features

• Renders publication quality graphics to SVG, PNG, Postscript, PDF and PGF
• Intuitive and consistent interface
• Works with Jupyter notebooks via IJulia out of the box

Installation

The latest release of Compose can be installed from the Julia REPL prompt with

julia> Pkg.add("Compose")

This installs the package and any missing dependencies. From there, the simplest of graphics can be rendered to your default internet browser with

julia> using Compose
julia> compose(context(), circle(), fill("gold"))

Now that you have it installed, check out the Tutorial and the Forms gallery.

Influences

Compose is intended as a futuristic version of the R library grid, and so takes a few ideas from grid. The Compose canvas is roughly equivalent to a viewport in grid, for example. Compose was also inspired by the admirable Haskell library Diagrams.
