Project: QGIS
Version: 2.10.0
Renderers are the subsystem of QGIS that allow you to create rich cartographical representations of your data. A graduated renderer varies the symbology based on a continuously changing value in a vector layer. In previous versions of QGIS you could only vary the colour (e.g. by using a colour along a colour ramp). In QGIS 2.10, the graduated symbol renderer now allows you to to vary size or the colour. For point layers you can vary the point size, for lines you can vary the line width. Polygon layers retain only the ability to vary by colour, line width is not yet supported.
