/**
 * 业务场景 Demo 17：项目审批数量趋势（政务/项目监管平台）
 *
 * <p>业务场景：项目监管平台按月统计「受理 / 审批通过 / 退回补正」三类的项目审批数量，
 * 用于观察审批负荷与办理质量的变化。</p>
 * <p>实际图表类型：{@link JChartType#BAR} 柱状图（分组柱，用于对比三类审批结果）。</p>
 *
 * <p>模板：{@code report/biz/17_project_approval.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\17_project_approval.pdf}。</p>
 *
 * <p>图表尺寸说明：图表按 700pt × 380pt（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/17_project_approval.txt");
