What advantages does data visualization have over conventional charts and graphs?

Conventional charts and graphs are limited in several ways: Most types can show only a limited number of data points before becoming too cluttered to interpret,they often can't show complex relationships among data points,and they can represent only numeric data.As computer technologies continue to generate large amounts of data that can be combined and connected in endless ways,a diverse class of display capabilities known as data visualization work to overcome all these drawbacks.In some instances,data visualization is less about clarifying individual data points and more about extracting broad meaning from giant masses of data or putting the data into context.
