/**
 * OtelMetricsChart – Type-aware ECharts visualisation for OTEL metrics.
 *
 * Renders one chart section per `metric_type` (`sum`, `histogram`, `gauge`,
 * and any other type present) with an appropriate chart style:
 *
 * - **sum** (counters): area-line chart with gradient fill
 * - **histogram**: bar chart with grouped series
 * - **gauge**: plain line chart (no area fill)
 * - **other**: falls back to area-line
