/**
 * 业务场景 Demo 33：资金流向树图表（集团资金管理）
 *
 * <p>业务场景：集团资金管理中心展示「集团总部 → 各业务板块 → 各项目公司」三级资金流向层级结构，
 * 用于投融资决策委员会分析资金沉淀与周转效率。</p>
 * <p>实际图表类型：{@link JChartType#Tree} 树图（层级水平布局，展示资金归集与下拨的父子层级）。</p>
 *
 * <p>模板：{@code report/biz/33_fund_flow_tree.txt}；树图以 SVG 文本形式绑定到模板的 {@code ${svg}} 占位符，
 * 输出到 {@code D:\test\biz\33_fund_flow_tree.pdf}。</p>
 *
 * <p>图表尺寸说明：树图渲染器画布固定 1000pt × 800pt（宽 × 高），节点总数控制在 12 个（1 个一级 + 3 个二级 + 8 个三级）
 * 以避免拥挤；模板中 {@code <svg>} 只声明宽度、不声明高度，宽度被页面自动收窄时高度按原比例同步缩放，不会纵向拉伸变形。</p>

Minimal invocation (3 lines)

Skip the full test class — the core is these three lines: bind the chart SVG, execute the template, get the PDF bytes. Copy them straight into your project.

// 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/33_fund_flow_tree.txt");
