visualointi

Visualointi is the Finnish term for visualization. It refers to the practice of representing information, data, or concepts in visual forms to enhance understanding, analysis, and communication. The field spans data visualization, information design, and visual reasoning, and it encompasses both static graphics and interactive media.

Common forms include charts such as bar, line, and pie charts; plots like scatter and histogram; geographic maps; diagrams (flowcharts, network diagrams, circuit diagrams); infographics; and interactive dashboards. More advanced forms include 3D visualizations and immersive techniques in virtual or augmented reality.

Applications are widespread: scientific research, engineering, business intelligence, education, journalism, urban planning, healthcare, and public policy. Visualization supports exploration of data, comparison of scenarios, and presentation of uncertainty or variability.

Key principles include clarity, accuracy, and honesty; reducing clutter; appropriate encoding of data through color, size, and position; attention to accessibility and color vision deficiencies; and clear labeling, scales, legends, and context to prevent misinterpretation.

Common tools and workflows include spreadsheet software, Tableau, Power BI, and programming libraries such as Python's matplotlib, seaborn, and plotly, or R's ggplot2. Standards often involve vector formats like SVG for figures, and iterative processes that combine data preparation, sketching, and user feedback.
