Make your data go from just tabulated figures to a visual story to tell. See whether those figures trend upward, downward, or not at all along a time series. Use a scatterplot to determine whether or not two variables may have any correlation. Compare population densities among several metropolitan areas with maps. These are some of the ways in which data visualizations can be used to inform policy making, allocate resources, spot outliers, plan the next course or courses of action, etc.
Below, please select from among the available information about data visualization tools.
