Julia is a preferred language for data science, artificial intelligence, and modeling and simulation applications. The language combines the ease of use of Python and R with the speed of C++, while providing parallel computing capabilities out of the box.

Here are eight popular data visualisation libraries in Julia language.

(The list is in alphabetical order)

1| GadFly.jl

About: GadFly.jl is a popular statistical plotting and data visualisation library written in Julia. The library is influenced by the native Grammar of Graphics Plotting (GGPlot) library and is well suited to 2D statistical plots and more. The features of this library are-

• The library renders the publication-quality graphics to PDF, PNG, SVG as well as Postscript.
• It provides an intuitive as well as consistent plotting interface
• The library works with Jupyter notebooks via IJulia 
• It provides light integration with DataFrames.jl
• Supports an extended number of common plot types

2| Google Charts

About: Google Charts.jl is a Julia interface to Google Charts. A Google chart involves basically four steps, which include a specification of chart options as well as Google DataTable, a call to make the type of chart desired and a call to draw the chart. This package allows a number of functions to be done within Julia by-

• It helps in mapping DataFrame objects into Google DataTable.
• It provides mapping a Dict of options into a JSON object of chart options. 
• The package provides several constructors to make the type of chart, among others.

3| Makie.jl

About: Makie.jl​ is a ​popular plotting library for Julia, that provides an interface for ​GLVisualize​, with emphasis on interactivity and speed. It is a high-performance, extendable, and multi-platform plotting ecosystem for the Julia programming language. One of the popular features of this library is that it utilises Observables that make it easy to write visualisations, which can be updated dynamically with new data. An Observable is a container object which notifies all its listeners whenever its content changes.

4| Plots.jl

About: Plots is a popular plotting API and toolset. Plots.jl is a plotting metapackage, which is basically an interface over many different plotting libraries. In Plots.jl, every column is a series, i.e. a set of related points which form lines, surfaces, or other plotting primitives. Some of the feature of Plots.jl are-

• Concise: Less code and more efficient development/analysis.
• Flexible: Produce favorite plots from favorite packages in a quicker and simpler way.
• Consistent: No need to commit to one graphics package, use the same code everywhere.
• Lightweight: Very few dependencies.

5| PyPlot.jl

About: PyPlot.jl provides a Julia interface to the Matplotlib plotting library from Python, and specifically to the matplotlib.pyplot module. PyPlot uses the Julia PyCall package to call Matplotlib directly from Julia with little or no overhead. This package takes advantage of Julia’s multimedia I/O API to display plots in any Julia graphical backend, including as inline graphics in IJulia.

6| PGFPlotsX.jl

About: PGFPlotsX is a Julia package to generate publication quality figures using the LaTeX library PGFPlots.It draws high-quality function plots in normal or logarithmic scaling with

a user-friendly interface directly in TEX.  It supports line plots, scatter plots, piecewise constant plots, bar plots, area plots, mesh and surface plots, patch plots, contour plots, quiver plots, histogram plots, box plots, polar axes, ternary diagrams, smith charts and more. 

 Some of the features of this package are –

• Showing figures inline in Jupyter notebooks, Juno and VSCode-julia. Both png- and svg-figures can be shown.
• Exporting to tex, pdf, svg, and png, file formats.
• Customising the preamble so that commands from latex packages can be used.
• Extra functionality when different packages are loaded, for example Colors, DataFrames, Contour etc.

7| UnicodePlots.jl

About: UnicodePlots.jl is an advanced Unicode plotting library designed for use in Julia’s REPL. Using this library, one can generate plots like scatterplot, lineplot, barplot, histogram, boxplot, density plot and heat map.

8| VegaLite.jl

About: VegaLite.jl is a plotting package for the julia programming language. It is based on Vega-Lite, which extends a traditional grammar of graphics API into a grammar of interactive graphics. It allows users to create a wide range of statistical plots.
