Should Salesforce be granted a patent on 'Visualizing Hierarchical Data'?

Granting a patent to Salesforce for 'Visualizing Hierarchical Data' raises concerns about the novelty and non-obviousness of the concept. Visualizing hierarchical data is a common requirement in many applications, and it's arguable that this is an obvious extension of existing data visualization techniques. Allowing a company to patent such a broad concept could stifle innovation in the field.
