Geovisualization

This section uses COVID-19 case data for Illinois counties, including the City of Chicago, to demonstrate how different visualization techniques support different analytical goals. While both tasks use the same dataset, each visualization emphasizes a different way of understanding the data. Task 4: COVID-19 Cases by County (Dot Chart) The dot chart displays total COVID-19 cases for Illinois counties and the City of Chicago, with each geographic unit represented as a single point on a shared horizontal scale. This design allows for quick and direct comparison across counties. To improve readability and focus on meaningful patterns, the chart is filtered to include only counties with more than 5,000 cases. Applying this threshold reduces visual clutter and highlights counties with the highest case counts, making differences between counties easier to identify. Overall, the dot chart is effective for ranking and comparing case totals across many geographic units. Tas...

This section presents Tasks 1–3 from Lab 2, based on Chapters 4 and 6 of Communicating Data with Tableau . These tasks use ratios, ranking, and distribution-based visualizations to examine recycling behavior and refuse production across New York City community districts and boroughs. The visualizations follow examples from the textbook and are implemented using Tableau. Task 1: Ratio of Recycling to Refuse by Community District The data show recycling and refuse collection for New York City community districts, organized by borough. By expressing this information as a recycle-to-refuse ratio, the chart allows districts of different sizes to be compared fairly. The pattern shows that recycling performance varies across boroughs and also among districts within the same borough, revealing spatial differences that are not clear from total amounts alone. Task 2: Ranked Recycling to Refuse Ratio This view uses the same recycling and refuse data but orders community di...

Lab 1: Column Chart Example from Chapter 2 (Figure 2-12) This lab is based on Chapter 2 of the book Communicating Data with Tableau by Ben Jones. The goal of this chapter is to understand the Tableau interface and learn how data can be explored and communicated using basic visualizations. The New York Boroughs dataset was used to create a column chart that compares population across different boroughs. This chart makes it easy to see which boroughs have higher or lower population values. The exercise demonstrates how drag-and-drop tools in Tableau can be used to quickly create clear and effective charts for communicating data patterns. Lab 1: Population Density Map of New York Boroughs (Figure 2-13) This map follows the example shown in Chapter 2, Figure 2-13 of the book Communicating Data with Tableau by Ben Jones. The map displays population density across the New York boroughs, allowing spatial differences to be seen more clearly than in a chart. Colo...
