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
byte[] pdf = new JQuickPdfFactory(config).executeResource("report/biz/82_credit_certificate.txt");
