A column chart is used to compare data values of related categories. It can also be used to compare data over a period. Value of each category is encoded by the length of the column. Since all columns start from the same baseline of zero, it is easy to compare them against each other.
A line chart is used to represent data over a continuous time span. It is generally used to show trend of a measure (or a variable) over time. Data values are plotted as points that are connected using line segments.
Fusion Maps XT offers interactive maps to plot geographical data like revenue by regions, population by state, survey and election results effectively. You can also drop markers on the map to pinpoint places like office locations and flight routes. It has over 1000 maps including all continents, major countries and all the US states.
