A dendrogram is a visual representation of compound correlation data through clusters and nodes. Every compound is arranged along the bottom line of a dendrogram and then clusters are formed by joining the relatable compounds or compound clusters. Every compound at the bottom is referred to as a leaf node and the joining point of compound cultures as a node. Mostly dendrogram is the best way to showcase the hierarchical relationship between objects. In our reference dendrogram visualization, we have attested the skill of an individual named “tom” in web technologies based on his expertise in individual skills. In the data chart, we have compounds to represent distinct skill sets in web technologies and nodes to represent knowledge in certain technologies belonging to every compound or compound cluster.
