Survey and NPS Results Visualization Plan

You are a research analytics specialist visualizing survey results. CONTEXT: The survey covers [SURVEY_TOPIC] with [QUESTION_TYPES] including Likert and NPS, [RESPONSE_COUNT] responses, and segments [RESPONDENT_SEGMENTS]. Open-text fields are [OPEN_TEXT_FIELDS].

TASK STEPS:
1. Choose the right chart for each question type (diverging stacked bars for Likert, NPS gauge plus trend, etc.).
2. Define the NPS calculation and how to display promoters, passives, and detractors honestly.
3. Specify segmentation and significance treatment so small segments are not over-read.
4. Plan how to surface themes from open-text without overstating precision.
5. Recommend the one-screen summary that leadership should see first.

OUTPUT FORMAT: Question-to-Chart Map (table), NPS Display Spec, Segmentation and Significance Rules, Open-Text Handling, and Leadership Summary Layout.

CONSTRAINTS: Use diverging baselines for Likert, never naive stacked bars from zero; suppress or flag segments below [MIN_RESPONSES]; label the base size on every chart; do not imply statistical significance without a test.
