| S1-Map-Bar |
Week 3, David |
A map of bus routes with a simple bar chart. The map shows hotspots by color. The bar chart shows average delay by route. |
I wanted to show both geographical and quantitative data in a single view. The bar chart makes it easy to compare routes. |
Feedback from Lena: “The map is a great idea, but I need to see the delays over time, not just an average.” New idea: Add a time-series chart. |
| S2-Timeline-Map |
Week 3, David |
A timeline showing daily delays linked to a map. When you select a day on the timeline, the map updates to show delays for that day. |
This addresses the need for temporal analysis. Brushing and linking is a key interaction. |
Feedback from Lena: “This is much better. Can we also filter by type of day (weekday vs. weekend)?” New idea: Add a filter control. |
| S3-Heatmap-Scatterplot |
Week 3, Jessica |
A heatmap showing average delay by time of day and day of the week. A scatterplot of delay vs. precipitation is also included. |
This directly addresses the “correlation” task. The heatmap is a compact way to show a lot of data. |
Feedback from Lena: “This is exactly what I need to check my theories about bad weather.” This sketch will be the basis for a key part of the final visualization. |
