Recommended Julia Packages for Mera Workflows

Mera draws nothing itself. The tutorials plot with CairoMakie, and a few older projection pages use PyPlot, neither is a Mera dependency:

using Pkg
Pkg.add("CairoMakie")

Mera's Makie support is a package extension: it activates once a backend is loaded.

Packages that commonly pair well with Mera for astrophysical AMR / N-body analysis. None is required, Mera works on its own. For the wider Julia ecosystem beyond Mera workflows, see Essential Packages, which also marks which packages Mera already depends on.

Core Visualization

• PyPlot.jl: Matplotlib style publication plots
• Makie.jl: High‑performance interactive & GPU plotting
• PlotlyJS.jl: Web, interactive dashboards
• StatsPlots.jl: Quick statistical visualizations

Data Analysis & Tables

• DataFrames.jl: Tabular manipulation
• CSV.jl: Fast CSV I/O
• Arrow.jl: Columnar interchange (big tables)
• StatsBase.jl, Distributions.jl: Statistics & probability

Units & Physical Context

• Unitful.jl: Core unit system
• UnitfulAstro.jl: Astronomical constants & units

Numerics & Math

• FFTW.jl: Fourier transforms
• Interpolations.jl: Multi-D interpolation

Performance & Developer Tooling

(Included implicitly with Mera: BenchmarkTools, ProgressMeter)

• ProfileView.jl / StatProfilerHTML.jl: Profiling
• TimerOutputs.jl: Structured timing blocks

File Formats / I/O

(Included: JLD2 via Mera.JLD2)

• HDF5.jl: HDF5 ecosystem interoperability
