How to change picture marker symbol based on a feature attribute

Seems simple enough. Using the code below, how would I use a different symbol based on an attribute of the LatestLSRCSV layer? I assume I would need to create new "symbol" variables for each possible entry of the attribute that will decide the symbol?

		//Add LSR Event Layers
		var LatestLSRCSVtemplate = new InfoTemplate();
		LatestLSRCSVtemplate.setTitle("Local Storm Report Attributes");
		LatestLSRCSVtemplate.setContent(getLatestLSRCSVTextContent);
		var LatestLSR = new CSVLayer("./NewLSR.csv",{id:"LatestLSR",refreshInterval: 1.0,mode: FeatureLayer.MODE_SELECTION,outFields: ["*"],infoTemplate: LatestLSRCSVtemplate});
		var symbol = new PictureMarkerSymbol({"angle":0,"xoffset":0,"yoffset":0,"type":"esriPMS","url":"http://static.arcgis.com/images/Symbols/Basic/RedSphere.png","contentType":"image/png","width":22,"height":22});
		var renderer = new SimpleRenderer(symbol);
		LatestLSR.setRenderer(renderer);
		map.addLayer(LatestLSR);
		LatestLSR.hide();

Hi Charles,

Take a look at using the UniqueValueRenderer. An example can be found here.
