No need to apologize - I was just trying to determine what styling aspects you thought were most important and could be improved 
In the image you shared it seems like the readability of the captions could be improved by increasing the length of the relationships and spacing nodes further out. This can be accomplished by reducing the "springiness" of the the relationships for the physics simulation that determines layout and can be configured in vis.js (the underlying visualization library used by neovis.js). Unfortunately, we don't expose much of that configuration in neovis.js. There are a few open issues requesting this.
Neovis.js was originally conceived to have all styling optimized and specified by results of graph algorithms (like centralities, community detection, etc) and most generic graph visualization features are currently lacking or not exposed from vis.js. As more folks are using neovis.js for more generic graph visualization and not necessarily to visualize the results of graph algorithms we'll need to update neovis.js to support these use cases - which is something we want to do. In the mean time, you might have better luck using vis.js directly and then you'll have all of the styling / configuration available.
