1、配置数据类型
    	data:[
    		{
    			name:'节点名称',
    			value:'节点值'
    			x:节点坐标,	在不指定的时候需要指明layout属性选择布局方式。
    			y:节点坐标,
    			symbolSize: 80,
                draggable: true, 	节点是否可拖拽，只在使用力引导布局的时候有用。
                itemStyle: {},
                categrory:'在categories中设置的名称,用于图例等分类'
    		}
    	]
    
    2、配置series
    	series:[{
    		 type: 'graph',
             layout: 'force',
    		    'none' 不采用任何布局，使用节点中提供的 x， y 作为节点的位置。
    		    'circular' 采用环形布局，见示例 Les Miserables，布局相关的配置项见 graph.circular
    		    'force' 采用力引导布局，见示例 Force，布局相关的配置项见 graph.force
    
             force: {	力引导布局相关的配置项
                 repulsion: 30,	节点之间的斥力因子。
                 edgeLength: 10	边的两个节点之间的距离，这个距离也会受 repulsion。
             },
             roam: true,	是否开启鼠标缩放和平移漫游
             label:{},
             categories:[{name:'图例名称',itemStyle:{color:图例颜色}},{name:'图例名称',itemStyle:{color:图例颜色}}]
             links:[
    			{
    			  source: "哪个节点的name",
                  target: "连接到哪个节点的name"
    			}
    		]
    	}]
    	
    3、设置图例 
    	legend:{}  设置了categories和category后,通过categories控制图例颜色
