最小调用（3 行）

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/credit_report_11_matrix.txt");

模板文件 · 11_matrix.txt

类 HTML + 内联 CSS 的模板语法，绑定数据后渲染为 PDF。下方为完整模板，可直接复制，也可下载原始文件。
