<contour>

The <contour> tag specifies a line contour plot to appear within the context of a map. As such, <contour> tags can only appear as children of a <map>. Each <contour> tag must contain a single <data> tag, and may contain a <range>, <lineStyle>, and <textStyle>. If the <range>, <lineStyle>, or <textStyle> is omitted, defaults will be applied. Currently, the data source for a contour plot is limited to an MDF formatted file. Future versions may allow for additional contour data sources.
