vega-desktop's Introduction

Vega-Desktop

App for viewing visualizations created in Vega or Vega-Lite. We are not always keeping the versions of Vega and Vega-Lite up to date. Please use the Vega-Editor to work with the latest versions.

Download from GitHub releases.

To download versions before 2.0, please see CHANGELOG.

Features

Can read both Vega and Vega-Lite files.
Save output as svg or png from UI.
Can determine the file format if the extension is *.vg.json or *.vl.json.
If the extension is just *.json, will check for $schema field in the JSON spec.
Otherwise will try to parse as Vega-Lite, then Vega.
It will load external data files relative to the spec files directory.

You also can set your OS to have *.vg.json or *.vl.json opened with vega-desktop by default.

Dev

yarn
yarn start

Build

yarn build

Builds the app for OS X, Linux, and Windows, using electron-packager.

vega-desktop's Issues

installation?

Could you please provide a full example on how to install vega-desktop on a local win10 machine? I cloned the repository but I fail to use yarn properly. I installed yarn from here YARN, but nothing happens. "could not find yarn" it says when I run "yarn start" in the vega-desktop folder.

sorry for this lame question, but i am sure many people will not be able to solve this question.

Add the possibility to download in svg

It will be very useful to not only view a visualization but also to download it for reuse in static project.

Specify baseurl

When I load a vega spec but the data is in a separate directory so the relative links are not correct, I'd like to specify the baseurl so that my specs render correctly. I can imagine a directory selector in the UI. However, I understand if you want to keep the App lean.

Feature request: generating static images from command-line

This is a feature request.
I need to generate static images in PNG or other format by calling the application from command-line. The input is json specification. Is it feasible to implement in vega-desktop ?

Feature Request: cycle through charts within the same directory

You know how with a lot of image viewers you can use the arrow keys or buttons to cycle through all the images within one directory?

How hard would it be to do something like that with vega-desktop?

Allow Loading Data via Symlink

I symlink data folder to specs in Vega-Lite but still can't open them.

Debugging capabilities

It would be very useful if I could use vega-desktop to debug vega visualizations. Currently some error messages are printed, but without any context such as where they appear. Furthermore, printing the value of VEGA_DEBUG (see https://vega.github.io/vega/docs/api/debugging/) would provide much of the information needed.

If access to the Chrome dev tools is possible, all this could be accomplished.
