/**
 * 业务场景 Demo 27：企业运营业务指标热力矩阵（企业运营）
 *
 * <p>业务场景：企业运营管理系统按"业务线 × 月份"汇总营业收入，通过颜色深浅识别各业务线的
 * 淡旺季规律，为资源投放与营销排期提供依据。</p>
 * <p>实际图表类型：{@link JChartType#HEATMAP} 热力图（矩阵单元格颜色越深表示营收越高）。</p>
 *
 * <p>模板：{@code report/biz/27_metric_heatmap.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\27_metric_heatmap.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/27_metric_heatmap.txt");
