Study Notes
Design Choices in Data Visualization
- Analyzing design choices helps identify appropriate visualization methods based on data characteristics.
- Single-value visualizations (like option 8) are deemed unnecessary; such options can be excluded from consideration.
- It's crucial to document reasons for design choices in design documents to inform future decisions.
Understanding Data Choices and Visualizations
- Data groups with one attribute (1x4 arrays) are unsuitable for complex visualizations like clustered bar charts or stacked bars.
- Trend visualizations (like line charts) are inappropriate for discrete values; they should reflect continuous data.
- Radar charts require multiple dimensions; thus, they are often inapplicable for single or dual attribute data.
Narrowing Down Design Options
- Initial options can be reduced significantly by excluding non-viable visualization methods based on data type.
- Design constraints should also be evaluated to refine potential choices further.
- Currently, 15 visualization options remain after applying these criteria.
Limitations of Specific Chart Types
- Pie charts are limited to univariate data; they are ineffective for bivariate datasets such as those labeled 5, 6, and 7.
- Visualizations must align with the data’s dimensionality and characteristics to ensure their effectiveness.
