The Vega Project is happy to announce the release of version 5.3.0 of the Vega-Altair Python visualization library. This release has been 4 months in the making and includes enhancements, fixes, and documentation improvements from 11 contributors. Highlights in 🧵

Do you use shell scripts? 🐚 📜

I'm conducting a study of how new tools might help. I'd love to talk with you about your shell experiences, and to run our new prototype by you.

Interested? Heck yeah you are, here's a form:

(Novices & experts plz!)

Observable Framework 1.3 🆕 integrates Interactive Data Lab’s Mosaic vgplot, which can concisely expressive performant coordinated views of millions of data points. observablehq.com/framework/lib/…

I've always been excited about the hybrid client/server execution model in MotherDuck but seeing how well the WebAssembly client works with Interactive Data Lab Mosaic is even more exciting.

In the video below I am looking at 10m data points in my browser.

If you’re excited about Observable Framework’s new SQL cells, wait till you see our Mosaic integration! The code:
---
sql:
gaia: ./gaia-sample.parquet
---

# Hello, vgplot

```js echo
vg.plot(vg.raster(vg.from('gaia'), {x: 'ra', y: 'dec', fill: 'density'}))
```

Do you make visualizations with Vega-lite, Altair, or Plot.ly? Have you have used their example galleries? If so please participate in our (paid!) study! (30min/15$)

We want to understand how/why folks use galleries

To sign up, fill out the survey linked below!

I've had fun playing with Observable Framework to deploy dashboards and web apps. Here's an example site integrating Interactive Data Lab Mosaic and @DuckDB for scalable visualization: uwdata.github.io/mosaic-framewo…

While data sonification is a key method for accessible & immersive experiences of data, creating them can be tedious with current tech support. Our #CHI24 paper presents *Erie*, a declarative grammar for data sonification. 1/12

You can add alt texts to figures in LaTeX with `alt={...}`.

The alt texts won't necessarily appear in the generated PDF until new versions of LaTeX but let's start with this good practice now.

Are you a US ugrad student interested in doing summer research in HCI? We've just opened up applications for our DUB Undergraduate Summer REU program!

Interns will be matched with a HCI & Design at UW faculty mentor. ~9 weeks, paid, on UW campus. Deadline is 2/2:

The Vega Projects now have a charter, steering committee, documented governance, and easier ways for people to become maintainers at github.com/vega/.github.

There's another delightful return to #ieeevis this year: the West Coast Party strikes again! Tonight (Tue), 9pm-midnight, at the Emerald Peacock. Co-hosted by Tableau, UBC, UW, and UVic.

Congrats to IDL co-director Leilani Battle (Leilani Battle) for the 2023 VGTC Significant New Researcher Award! #IEEEVIS2023 ieeecs-media.computer.org/tc-media/sites…

Really enjoying playing with Interactive Data Lab 's Mosaic, linking DuckDB with Observable plot feels so natural and responsive - just a joy

I’m looking for PhD students in CS at UUtah, starting fall 2024. I’m excited about problems in InfoVis (eg DSLs, dashboards, linters, etc) and programming interfaces (eg creative coding, notebooks, spreadsheets, etc). Come build cool tools and theories with me!

I’m excited to announce my IEEE VIS 2023 paper “EVM: Incorporating Model Checking into
Exploratory Visual Analysis” with Ziyang Guo, Emily Qiao, Jeffrey Heer, Jessica Hullman

To help IEEE VIS authors make accessible PDFs for #ieeevis2023 , I made a video where where you can watch me add tags and alt texts to a paper made with LaTeX. youtube.com/watch?v=N8sjpJ…
