/**
 * 业务场景 Demo 39：客户分层饼图（企业运营 / 客户经营）
 *
 * <p>业务场景：企业运营平台按客户价值把活跃客户划分为战略客户、重点客户、成长客户、
 * 一般客户、潜在客户五层，用于客户经营策略与资源投放决策，主色采用商务稳健蓝 #0D47A1。</p>
 * <p>实际图表类型：{@link JChartType#PIE} 饼图（展示各客户层级的数量占比）。</p>
 *
 * <p>模板：{@code report/biz/39_customer_segment_pie.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\39_customer_segment_pie.pdf}。</p>
 *
 * <p>图表尺寸说明：图表按 700pt × 400pt（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>

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/39_customer_segment_pie.txt");
