Discussion - Best chart for the data
This is a group discussion. The trainer shows several different visualisations of the same dataset.
- Vote for the visualisation that you like most and like least
- Explain why you have made your vote
Hopefully, we pull out some principles the most appropriate chart for a
given dataset and situation!
Which chart type should we choose, based on the purpose?
Here are some “rules of thumb” to chosse a chart depending on the purpose.
- Compare A vs B: bar chart, small multiples
- Composition: pie, tree map, 100% stacked bar
- Show trends over time: line chart, area chart
- Show relationship between two (numeric) quantities: scatter plot
- Show distribution of data (min, max, median , outliers): box-plot, histogram
- Show contribution to total: waterfall chart
- Highlight a critical value: card
- Show data with a place aspect: shape map, point map
- Show flows from source to destination: chord, Sankey diagram
