Overview This Power BI Custom Visual is an open‑source radar chart (also known as a spider graph) designed for presenting structured, category‑based data on a fixed scale. It displays multiple category values on a 1–5 scale arranged radially, making it easy to compare strengths, weaknesses, or patterns across dimensions. At the center of the chart, the visual calculates and displays an overall index value, computed as the average of all category scores and scaled to a 0–100 range. The visual is distributed under the MIT License, provided free of charge, and contains no telemetry, tracking, or external data connections. Value Proposition The visual provides a clear and intuitive way to summarize multi‑dimensional assessments, especially when the underlying data comes from surveys, questionnaires, or scoring frameworks. Its key advantages include: Purpose‑built questionnaire visualization, offering a natural way to display responses that use a fixed 1–5 rating scale. Immediate insight through a central index, giving users a single, easy‑to‑interpret summary metric alongside detailed category values. Consistent and standardized presentation, ideal for organizations that rely on structured scoring models or repeated assessments. Open-source transparency, allowing teams to audit or extend the visual to meet internal standards. Strict data containment, ensuring all data remains within Power BI with no external communication, which is essential for regulated environments. Business Audience The visual is intended for analysts, report authors, and business teams who work with structured scoring data. Typical users include: HR and organizational development teams analyzing employee surveys, competency assessments, or 360‑degree feedback. Customer experience and service teams evaluating satisfaction surveys or quality assessments. Consultants and analysts presenting maturity models, capability assessments, or benchmarking results. Education and training organizations summarizing evaluation forms or learning outcome assessments. Product and UX teams visualizing user feedback or feature‑level satisfaction scores. Target Industries Because the visual is self‑contained, open source, and does not transmit data, it is suitable for a wide range of industries, including: Professional services and consulting, where capability assessments and maturity models are common. Human resources and talent development, where structured questionnaires are widely used. Healthcare, public sector, and finance, where data privacy and auditability are critical. Education and training, where standardized evaluation forms are frequently analyzed. Manufacturing and operations, where performance or compliance checklists use fixed scoring scales. Key Features Radar chart visualization optimized for 1–5 scale questionnaire data. Automatic index calculation, converting the average category score into a 0–100 metric for quick interpretation. Customizable formatting options to align with organizational branding or reporting standards. Lightweight and performant, suitable for dashboards with large datasets or repeated assessments. Fully open-source MIT‑licensed codebase, enabling modification, extension, and internal review. No external dependencies, ensuring full data privacy and compliance with strict security requirements. Intended Use Cases Presenting results from employee, customer, or stakeholder surveys. Visualizing competency or capability assessments across multiple dimensions. Summarizing questionnaire‑based evaluations in HR, training, or performance management. Displaying maturity model results in consulting or strategic planning.
