There may be display errors around missing values and changes as additional data is added and refined. Comparing hundreds of elements in an accessible way has various challenges and these sketches represent different ideas to visualize and understand the dataset. It also explores some ideas around navigating missing data as its own insight both in refining a dataset and in highlighting some of the challenges in transparency around transit constructions costs. I am interest in feedback around the usefulness of different aspects, what could be refined, additional features. Dataset Overview (Copy from December 3, 2020)
