The Queryverse has a powerful visualization story that is based on the Vega ecosystem. This talk will demonstrate how one can use the Vega family of packages to easily create simple and advanced visualizations with Julia and how the various packages are integrated with each other.
The Julia Vega ecosystem is made up of five packages and tightly integrated with the Queryverse. The packages that this talk will introduce are:
- VegaLite.jl: the core grammar of interactive graphics package that makes it easy to create powerful figures with ease.
- Vega.jl: if you need the power of the full Vega grammar, you can access it via this package. Creating figures with Vega.jl is more verbose, but gives you more control.
- QuickVega.jl: this package provides a simple imperative API to create complicated figures without a full grammar of graphics API.
- DataVoyager.jl: an interactive UI for data exploration that allows you to create Vega-Lite plots.
- Lyra.jl: another interactive UI that is WYSIWYG editor for powerful Vega figures.
I will also briefly on various front-ends that have native Vega and Vega-Lite support built in: ElectronDisplay.jl, the Julia VS Code extension, Jupyterlab and nteract.

He co-develops the integrated assessment model FUND that is used widely in academic research and in policy analysis. His research has appeared in Science, the Journal of Environmental Economics and Management, Environmental and Resource Economics, the Oxford Review of Economic Policy and other academic journals. He contributed a background research paper to the Stern Review and has advised numerous organizations (including US EPA and the Canadian National Round Table on the Environment and the Economy) on the economics of climate change.
He is an assistant professor in the Energy and Resources Group at the University of California, Berkeley. Previously he was an assistant professor in the School of Natural Resources and the Environment of the University of Michigan, a postdoc at the University of California, Berkeley and a postdoc at the Economic and Social Research Institute in Ireland. He also was a visiting research fellow at the Smith School of Enterprise and the Environment, University of Oxford.
He holds a PhD (Dr. rer. pol.) in economics from the University of Hamburg (Germany) and the International Max Planck Research School on Earth System Modelling, a MSc in Environmental Change and Management from the University of Oxford (UK) and a M.Phil. in philosophy, logic and philosophy of science from Ludwig-Maximilians-Universität München (Munich, Germany).
