```chart
type: histogram
title: Build durations (seconds)
data:
  inline:
    - { duration: 42 }
    - { duration: 48 }
    - { duration: 55 }
    - { duration: 58 }
    - { duration: 61 }
    - { duration: 63 }
    - { duration: 66 }
    - { duration: 71 }
    - { duration: 73 }
    - { duration: 78 }
    - { duration: 89 }
    - { duration: 94 }
    - { duration: 112 }

Fields that matter

• type: histogram with encoding.x as the numeric observation field
• binning.count sets 1 to 256 equal-width bins; the default is Sturges
• binning.extent limits the range; binning.edges sets explicit boundaries
• binning.measure is count (default), proportion or density
• encoding.color stacks groups within each bin and encoding.facet splits panels
• encoding.y is not supported; the engine calculates the measure

Interactions

• Hover or focus a bin to read its range and measure.
• Click a legend entry to toggle a group when colors are used.
