Data visualisation allows you to:
- Extract valuable information and patterns from data
- Communicate this in a clear and comprehensible visual representation
- Enhance the communication of research findings, making it accessible to a broader audience
- Identify data quality issues, as outliers and data errors may become more visible in visualisations
Therefore, data visualisation is an aspect of research data management!
Below follow some resources that may help you in creating clearer, more accessible and more transparent data visualisations.
Tools¶
- Datawrapper, where you can upload your data to generate tables and charts.
- upset graphs are a straightforward way to visualize set intersections in a matrix layout, which can help in analysing multiple datasets at once.
- Using Python Plotly you can add annotations and animations as extra visual cues to highlight important features.
- Annotating visualisations in Python plotly (blog and video)
- Animations using Python plotly
