This is an OASIS TC Open Repository. See the Governance section for more information.

The STIX visualization is meant to provide producers and consumers of STIX content with a rapid way to visualize the objects in a STIX JSON file, and the relationships between those objects. The visualization is implemented in HTML, CSS, and JavaScript (using the D3.js library), and is suitable for standalone use — either on a hosted server or as a local file — or embedded into other applications. Regardless of how deployed, the JavaScript code in this repository does not transmit STIX data to any server; it is strictly processed within the browser in which the code is running, so it is suitable for data which the user does not wish to share.

It visualizes STIX 2.0 content using d3, and is 100% browser-based, meaning that you can use it without sending all your data to the server (great!)

This code makes a lot of assumptions! It assumes:

• The source - a file you upload, text you paste, or an external server - provides valid JSON
• That JSON has a bunch of keys and values, some of which are arrays
• Everything inside those arrays is an SDO, with an ID, type, and ideally title
• One of those arrays contains a list of relationships between the other SDOs provided

This should match most STIX 2.0 content inside a bundle. For a slightly out-of-date example, look at test.json.

Click on nodes or paths to get more detailed information for that element (and to pin nodes in place). If you want to unpin a pinned node, double-click it.

If you want to load another JSON file, just click on the title at the top of the page to go back to the input options.

Go to http://oasis-open.github.io/cti-stix-visualization. Upload a JSON file, paste some valid JSON text, or provide the URL for an external JSON file. The URL for an external JSON file can be provided on the main page or as a URL parameter: https://oasis-open.github.io/cti-stix-visualization/?url=https://raw.githubusercontent.com/oasis-open/cti-stix-visualization/master/test.json.

You can also optionally customize the text and icons associated with each object type, shown on the graph. There is a separate field that accepts JSON (format is specified on the visualizer page), and allows you to specify a custom icon and/or a custom property to be shown. You can specify one custom icon and/or display property per type of object; you can overwrite the icon and/or text displayed for existing STIX object types, or for your own custom object types. Note that the custom icon must be located in the visualizer's icons directory. Alternatively, you can specify the custom icon via a web URL, in which case you must specify the protocol (e.g. https).

You can integrate the visualizer into your own web application. The visualizer is implemented as an AMD module that exports the Viz class. You can create a new Viz instance and visualize your STIX content using code like the following:

visualizer = new stix2viz.Viz(mySvgElement);
visualizer.vizStix(content);

Finally, you can use visualizer.vizReset() if you need to clear the graph.

Documenting AMD is beyond the scope of this document. There are various implementations of it; this repository includes requirejs. Importing and using AMD modules generally looks like:

require(["module1", "module2"], function(module1, module2) {
    /* Do stuff with the modules */
});

So you need to add your AMD implementation to your web page, and then use modules as above. With respect to stix2viz, you may need further configuration to ensure the module is found, especially since it was written to work as a Jupyter notebook extension. You may consult index.html and application.js for inspiration.

To run a local copy of the STIX visualizer, just point your browser to index.html after you clone the repo.
