CSCE 5320 HW7 - Bike Sharing
Ten views rearrange the same Capital Bikeshare dataset to show how table order changes interpretation. Reusable bar charts compare monthly totals in alphabetical, value, and derived casual-share orders, while stacked and grouped bars use identical 84 month–weekday totals. Heatmaps reorder months by row means, and a donut chart summarizes totals. Parallel coordinates plot 731 daily records with the total axis moved from last to first. The D3 v7 SVG views use closure-based barChart and chainable ordering functions, with a control menu switching among figures. Data is 2011–2012 UCI Bike Sharing daily observations.

The ten views implement the supplied assignment with the UCI Bike Sharing daily dataset. The reusable closure-based barChart and chainable ordering follow the supplied starter7.html. All calculations are in index.html.

Original source: Hadi Fanaee-T (2013), Bike Sharing, UCI Machine Learning Repository. https://doi.org/10.24432/C5W894 . CC BY 4.0. Original daily CSV values are unchanged. Weather values remain normalized to avoid ambiguity in source unit conversion metadata.
731 daily observations cover 2011-01-01 through 2012-12-31. There are 12 months, 7 weekdays, 16 original columns, and all 84 month-weekday combinations. No blank values or duplicate dates were found.
Q1 bars show total rentals by month across both years. Derived ordering is the monthly casual-rental share. Q1 stacked and grouped charts use the same month-weekday rental totals and vertical domain. Q2 heatmaps use mean daily rentals by month and weekday, preserve the same sequential colour domain, and reorder only months by their unweighted row means. Q3 uses the same monthly totals for the donut and all 731 daily records for four-dimensional parallel coordinates. The second parallel view moves total rentals from the final axis to the first with every other setting fixed.
The initial view is Figure 8, the radial chart. Before viewing Figure 2, the student must record their own estimated top-five month ranking. The report must use that observation rather than an invented result.
View menu: 1-3 reusable bars; 4 stacked bars; 5 grouped bars; 6-7 heatmaps; 8 donut; 9-10 parallel coordinates.
The source weather variables temp, hum, and windspeed remain normalized. Weather category colours use codes 1 (clear/partly cloudy), 2 (mist/cloudy), and 3 (light rain/snow), the three categories actually present in the daily data. No season names are used because the archived readme and current repository describe those codes differently.
