求教！echarts关系图的圆环怎么放小一点

Question

echarts官网中给了一个圆形关系图的示例，因为这个圆形太大，导致边上的标签文字显示不完全，现在想要把这个圆形放小一点，让那个标签文字完全显示出来，应该怎么改呢

 option = {
    tooltip: {
        trigger: 'item',
        formatter: "{a} <br/>{b}: {c} ({d}%)"
    },
    legend: {
        orient: 'vertical',
        x: 'left',
        data:['直达','营销广告','搜索引擎','邮件营销','联盟广告','视频广告','百度','谷歌','必应','其他']
    },
    series: [
        {
            name:'访问来源',
            type:'pie',
            selectedMode: 'single',
            radius: [0, '30%'],

            label: {
                normal: {
                    position: 'inner'
                }
            },
            labelLine: {
                normal: {
                    show: false
                }
            },
            data:[
                {value:335, name:'直达', selected:true},
                {value:679, name:'营销广告'},
                {value:1548, name:'搜索引擎'}
            ]
        },
        {
            name:'访问来源',
            type:'pie',
            radius: ['10%', '25%'],

            data:[
                {value:335, name:'直达'},
                {value:310, name:'邮件营销'},
                {value:234, name:'联盟广告'},
                {value:135, name:'视频广告'},
                {value:1048, name:'百度'},
                {value:251, name:'谷歌'},
                {value:147, name:'必应'},
                {value:102, name:'其他'}
            ]
        }
    ]
};

你调整radius后面的百分值，调整完之后可以看效果,
