/**
 * 业务场景 Demo 37：项目状态分布（政府投资项目监管平台）
 *
 * <p>业务场景：项目监管平台按"在建 / 已完工 / 前期 / 暂停"四大状态对政府投资项目分组，
 * 以矩形面积表示项目投资额，用于把握投资进度与资金沉淀情况。</p>
 * <p>实际图表类型：{@link JChartType#TREEMAP} 矩形树图（矩形面积正比于投资额，同色系为一组状态）。</p>
 *
 * <p>模板：{@code report/biz/37_project_status_treemap.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\37_project_status_treemap.pdf}。</p>
 *
 * <p>图表尺寸说明：图表按 700pt × 420pt（宽 × 高）的横版比例设计；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>

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/biz/37_project_status_treemap.txt");

模板文件 · 37_project_status_treemap.txt
