In all the previous chapters, we've created various visualizations and all these visualizations are either individual charts or analysis. Individual charts or analytics provide specific and limited information, like a single piece of a larger puzzle. As we put the pieces together, a larger picture takes shape. This is what we do on a dashboard. A dashboard is a collection of several worksheets and their supporting information put together to convey a broader perspective. A dashboard allows us to facilitate interactivity between individual worksheets, provides a unified view to present or to compare a variety of information and disseminate this information in a structured and fluent manner.
