Visualising hypergraphs

Force-directed drawing of hypergraphs

Motivation:

Datapoints in many real-world dataset are not necessarily dyadic in nature, e.g. relation between authors in a scientific article. Hypergraphs are generalisation of graphs that can naturally represent such data.

A hypergraph consists of a collection of points called vertices and a collection of subset of those vertices called hyperedges.

Contributions:

Under the supervision of Stephane Bressan, I implemented Hypervis, a platform for drawing hypergraphs using Fructherman-Reingolds force-based graph drawing algorithm. Currently it supports subset-based, edge-based and zykov-based drawing.

Here is a demo of Hypervis.

Caption photos easily. On the left, a road goes through a tunnel. Middle, leaves artistically fall in a hipster photoshoot. Right, in another hipster photoshoot, a lumberjack grasps a handful of pine needles.
This image can also have a caption. It's like magic.

You can also put regular text between your rows of images. Say you wanted to write a little bit about your project before you posted the rest of the images. You describe how you toiled, sweated, bled for your project, and then… you reveal its glory in the next row of images.

You can also have artistically styled 2/3 + 1/3 images, like these.

The code is simple. Just wrap your images with <div class="col-sm"> and place them inside <div class="row"> (read more about the Bootstrap Grid system). To make images responsive, add img-fluid class to each; for rounded corners and shadows use rounded and z-depth-1 classes. Here’s the code for the last row of images above:

<div class="row justify-content-sm-center">
    <div class="col-sm-8 mt-3 mt-md-0">
        {% include figure.html path="assets/img/6.jpg" title="example image" class="img-fluid rounded z-depth-1" %}
    </div>
    <div class="col-sm-4 mt-3 mt-md-0">
        {% include figure.html path="assets/img/11.jpg" title="example image" class="img-fluid rounded z-depth-1" %}
    </div>
