Line Graph

Line Graph URL
Line graphs are a type of geovisualization where data is designed with dots connected by lines.  The trend line averages all the data creating an easier way to view it.  In this graph, minimum wage is measured over a 70 year period.  The graph shows that minimum wage has slightly incresed every ten years.  In 196, the minimum wage was only one dollar, but in 2000, it was over five dollars.  Line graphs are an easy way to compare data over a certain amount of time.
