# vega-view

I am not 100% convinced this is a worthwhile project, but let's see how
it goes. You can think of it as "I want
[vega desktop](https://github.com/vega/vega-desktop) but don't want
to install an electron application, so decided to write an inferior
product" project.

The aim is to make it easy to view
[Vega](https://vega.github.io/vega/)
and
[Vega-Lite](https://vega.github.io/vega-lite/)
specifications - i.e. the JSON representing a visualization - as
a visualization. It relies on
[Vega Embed](https://github.com/vega/vega-embed) to do all
the hard work, and just provides a basic web server that:

 - you can drag-and-drop files onto to view them;
 
 - and will list the files in a given directory and, when selected,
   view them inline or on a separate page.

## License

This is released under a BSD3 license.

## Usage

The server - called `vega-view` - should be run from the directory
containing the specifications to view. It then provides a web server
on port 8082 that can be used to view them at the URL

    http://localhost:8082/display/

Visualizations can either be viewed as their own "page", or inline,
which may be more useful when you have multiple plots to view.

The aim is to be run in a a directory structure where most, if not
all, the files are Vega or Vega-Lite specifications. This means that
the web server tries to parse each file as JSON, which could cause
memory- or time- issues if there are large non-JSON files in the
directory tree.

## GHC support

This is currently a **very basic** application, so will hopefully build
against a wide variety of GHC installations. There has been /no/ testing
on Windows.
