/**
 * 业务场景 Demo 25：渠道来源漏斗转化（信用平台 / 用户增长）
 *
 * <p>业务场景：信用平台统计广告投放、搜索引擎、渠道合作、老客推荐四类注册渠道的新增注册量，
 * 以漏斗形态对比各渠道获客贡献，用于投放预算分配，主色采用暖调深橙 #BF360C。</p>
 * <p>实际图表类型：{@link JChartType#Funnel} 漏斗图（展示各渠道新增注册量的递减分布）。</p>
 *
 * <p>模板：{@code report/biz/25_channel_funnel.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\25_channel_funnel.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/25_channel_funnel.txt");
