Déjàvis is a sandbox for data visualizations. It allows you to develop pluggable
visualizations in a declarative style and deploy them to dejavis.org. You no
longer need to start from a plain HTML file. The HTML frame is defined by the
sandbox. You can modify the HTML using placeholders (name, description, author)
which are specified in a
manifest.json file. Of course you can manipulate the
dejavis command line utility lets you create, serve and deploy your
1. Create a visualization using a skeleton
dejavis create your_vis
This generates a skeleton containing an example visualization. The example is written in CoffeeScript, which is really great for writing expressive code in less lines of code. For the visualization part Unveil.js is used. However this is just a starting point. You can throw everything away and use your favorite frameworks.
2. Adjust manifest.json
Meta information, like name, description, author are specified here. Also the scripts that should be loaded need to be set.
3. Serve it locally and start development
4. Publish to dejavis.org
You need to have your code in a public Github repository in order to deploy your work. The name property of the manifest.json file needs to be unique as your visualization will live at http://dejavis.org/your_vis.
This command isn't implemented yet. Please contact me via Github. I'll publish your visualization manually.
dejavis is a command-line utility written in CoffeeScript and running on Node.js.
The included server uses the Express.js web framework.
