Businesses today are flooded with data and are increasingly looking for ways to leverage data to improve their decision-making, business processes, strategy, and financial performance. Data visualization can play a key role in helping businesses unlock the value of data to achieve desired outcomes. For example, data visualization can help business analysts see patterns in data that are not apparent when looking directly at the raw data and are sometimes easily discernible through aggregated analysis and summarizing broader patterns in the data. Data visualization allows large amounts of data to be presented in concise forms that are easy for analysts and other users to process, understand, and communicate to each other. Making business decisions based on analytics often requires clear communication and shared understanding. For these reasons, data visualization can be the key to harnessing the power of “big data” to improve business decisions, processes, and strategies. This course provides an overview of data visualization methods and introduces the technologies and software used to visualize data in business.
