Abstract
This report presents a comprehensive evaluation of free and open-source data analysis and visualization tools, specifically assessing their performance and usability on consumer-grade personal computers. With the increasing emphasis on data-driven decision-making across diverse industries, access to effective data analytics tools has become crucial not only for professionals but also for students, educators, and small organizations. However, a significant portion of available tools are either optimized for high-performance systems or are restricted by paywalls, thereby creating substantial barriers for users operating on low-resource hardware, such as Intel i3 processors, 12GB RAM, and traditional HDD storage.
This research addresses a critical gap in existing literature by adopting a full-pipeline perspective, evaluating tools across all major stages of the data analytics workflow: data importing, preprocessing (cleaning, encoding, and transformation), visualization, and inference. Unlike prior studies that predominantly focus on isolated components like visualization, this study provides a holistic view. The tools selected for this investigation cater to both technical users (e.g., Python with Pandas, Matplotlib, and Seaborn) and non-technical users (e.g., GUI-based platforms like KNIME, Orange, and web-based spreadsheets). Through empirical testing conducted on a standardized hardware environment reflective of common low-end configurations, critical performance indicators including execution time, memory and CPU usage, and crash frequency were measured. Qualitative usability was also assessed based on ease-of-use.
The findings reveal notable differences in how tools perform and behave under constrained conditions, uncovering inherent trade-offs between flexibility, usability, and system resource consumption. This report offers practical recommendations for users seeking to choose the most suitable tools based on their technical comfort and hardware limitations. Furthermore, it provides a foundational understanding for future software development aimed at enhancing accessibility and efficiency in low-resource contexts, thereby contributing meaningfully to the evolving landscape of inclusive data analytics practices and informing tool designers, educators, and policymakers working toward digital equity.
