@echarts.BoxPlot(echarts.BoxPlotConfig{
  Label: "Request latency distribution",
  Categories: []string{"Development", "Production"},

    Name: "Latency (ms)",
    Data: []echarts.BoxPlotData{
      {Min: 18, Q1: 31, Median: 42, Q3: 58, Max: 94},
      {Min: 25, Q1: 44, Median: 62, Q3: 86, Max: 138},

Summary contract

Each category accepts one finite, ordered summary: minimum, first quartile, median, third quartile, and maximum. Multiple series share the same categories.
