/**
* 业务场景 Demo 31:商户行业分布(收单/商户运营平台)
*
* <p>业务场景:收单业务按行业大类汇总存量商户,并下钻至细分子行业,用于商户经营结构分析与
* 行业拓展策略制定。</p>
* <p>实际图表类型:{@link JChartType#SUNBURST} 旭日图。选题原拟用环形图,但 Demo 20 已使用
* {@link JChartType#Circle} 环形图,为避免图表类型重复,本 Demo 改用旭日图——旭日图本质上是
* 分层展开的同心环,既能呈现一级行业的占比,又能通过第二层环直观展示子行业构成。</p>
*
* <p>模板:{@code report/biz/31_merchant_industry_sunburst.txt};图表以 SVG 文本形式绑定到模板的
* {@code ${svg}} 占位符,输出到 {@code D:\test\biz\31_merchant_industry_sunburst.pdf}。</p>
*
* <p>图表尺寸说明:图表按 640pt × 460pt(宽 × 高)的方形比例设计;模板中 {@code <svg>}
* 只声明宽度、不声明高度,因此宽度被页面自动收窄时高度会按原比例同步缩放,不会纵向拉伸变形。</p>

不想读完整测试类?核心就是这三行:绑定图表 SVG,执行模板,拿到 PDF 字节流。可直接复制到你的项目里。
// config 可省略;svg 来自 JChartRendererFactory.renderChart(...),见下方完整源码
factory.bind("svg", svg);
byte[] pdf = new JQuickPdfFactory(config).executeResource("report/biz/31_merchant_industry_sunburst.txt");模板文件 · 31_merchant_industry_sunburst.txt
