Audience poll

Open a talk with a choice question and a confidence slider.

Use a short opening poll to understand the room without testing attendees.

questions:
  - id: role
    after_slide: 1
    type: single_choice
    prompt: "Which role best describes your current work?"
    options:
      - { id: application, label: "Application development" }
      - { id: platform, label: "Platform or infrastructure" }
      - { id: data, label: "Data or machine learning" }
      - { id: learning, label: "Learning or teaching" }
    results:
      attendee_visibility: live

  - id: confidence
    after_slide: 2
    type: slider
    prompt: "How familiar are you with today's topic?"
    min: 0
    max: 10
    step: 1
    labels: { min: "New to it", max: "Use it often" }
    results:
      attendee_visibility: after_close

The first chart can stay live to establish the interaction. Closing the second question before publishing its histogram reduces anchoring on early answers.
