lyra

I'd classify Lyra as a custom visualization design surface while tableau is more of a data exploration tool.

Number One — Lyra Quarx — daughter of a human and a Quarxium.

I don't really see how Lyra (or any GUI) could accomplish that conceptual feat.

If you feel that a micro controller is too low power, you can plug in a luckfox lyra which runs a proper linux with 128M of RAM.

Also, I don't see how the Lyra visualizations are comparable to D3...

Where Lyra is interesting IMO is in it's ability to make more custom visualizations without coding - seems like using some kind of grammar of graphics definition under the hood.

The author links to th CSS x86 project: > Yes, Lyra Rebane build a x86 CPU completely in CSS, but that technique is simply not fast enough for handing the game loop.

For the most part this level of vis customization has been restricted to writing a program - lyra feels a lot like a nicer visual ggplot designer in R - so it's nice to see someone making an attempt at bringing some of these capabilities into a gui.

Yes, I'm asking this (annoying) question even though the OP states, "Lyra is more expressive than interactive systems like Tableau, allowing designers to create custom visualizations comparable to hand-coded visualizations built with D3 or Processing."...yeah, but how exactly?

Lyra on the other hand is more of a photoshop like tool for producing unique data graphics.

Free software built for astronomy that appears to do what Tableau (and to some extent Lyra) does, without the gloss.

For most tasks in Lyra, you can simply drag-and-drop elements onto the visualization to make it respond the way you want.
