Wagner is the center of the Universe?

I've just finished a little project mapping the network of classical composer influences published at Classical Music Navigator. This awesome site was published over ten years ago by Charles H. Smith, an accomplished library scientist. The site contains a listing of 444 classical composers. For each composer there are links for "musical influences" and "has influenced" enabling the construction of a directed network of composer influence. Some initial analysis indicates a few interesting things - the graph is not fully connected, the degree distribution follows an exponential decay (more on this to come), and it shows a high level of community structure (C=0.21). When we look at a k-cores visualization of the network, we notice one node conspicuously at the center. This bright center of the classical universe is non other than Wilhem Richard Wagner with a total degree of 93. With the original author's permission, I hope to re-publish this data on the Semantic Web...
