/**
 * 业务场景 Demo 45：存量业务分层（资产运营 / 存量客户经营）
 *
 * <p>业务场景：存量业务管理按账龄（月）与综合收益率（%）对存量资产分层，气泡大小表示存量规模，
 * 颜色表示分层（核心 / 成长 / 观察），用于存量资产的结构诊断与经营策略调整。</p>
 * <p>实际图表类型：{@link JChartType#Bubble} 气泡图。选题原拟用散点图，但 Demo 29 已使用
 * {@link JChartType#SCATTER} 散点图，为避免图表类型重复，本 Demo 改用气泡图——气泡图在散点
 * 二维坐标基础上增加了"气泡大小=存量规模"这一维度，能同时表达账龄、收益率与规模三重信息。</p>
 *
 * <p>模板：{@code report/biz/45_stock_bubble.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\45_stock_bubble.pdf}。</p>
 *
 * <p>图表尺寸说明：图表按 700pt × 400pt（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>

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/45_stock_bubble.txt");
