 * 业务场景 Demo 42：应急事件地域分布表（应急指挥平台）
 *
 * <p>业务场景：省应急指挥平台按行政区划统计突发事件起数与响应时效，用于汛期风险研判与救援力量前置部署。</p>
 * <p>实际图表类型：{@link JChartType#Geo} 地图（GeoJSON 行政区划图，底图区域为四川省 21 个市/州）。</p>
 *
 * <p>模板：{@code report/biz/42_emergency_geo.txt}；地图以 SVG 文本形式绑定到模板的 {@code ${svg}} 占位符，
 * 输出到 {@code D:\test\biz\42_emergency_geo.pdf}。</p>
 *
 * <p>图表尺寸说明：地图按渲染器默认画布 800pt × 600pt（宽 × 高）绘制；模板中 {@code <svg>} 只声明宽度、
 * 不声明高度，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/42_emergency_geo.txt");
