Web Technology Clusters in Europe

(click picture to enlarge)

This map shows all the IT clusters in Europe. I derived it from European Cluster Observatory which created this map using employment data. There are three star sizes ranging from one to three depending on how large the clusters are. You should visit their site as it's more informative, interactive, and plots other clusters of other industries such as fishing, jewelry, auto, etc. Click on cluster mapping and chose category and stars.
