Project Overview
This project is a collaboration between Center for Spatial Research and Columbia Law School- Cities of Bail. Our work is to design and build a interactive data visualization website for showing bail bonds over 20 years in 5 American cities. The visualization is to investigate how bail bonds affect the make up of American communities, and find which communities are targeted by bail companies.
problem
How to cross reference two datasets and visualize 20 years trend and generate insights?
CROSS REFERENCE between 2 different datasets
Cross referencing in maps layer
To cross reference two datasets, bail bonds and income & socio background, to see the which income groups suffer more and having more bail bonds
Adjusting map visualization
I used Mapbox Studio to adjust the color and test different visualizations.
Addressing map layers accessiblity
To improve accessibility, I optimized map colors for contrast and tested them against four types of color blindness: Protanopia, Deuteranopia, Tritanopia, and Achromatopsia, ensuring critical elements stayed readable.
Cross referencing with charts
Test different options of charts to compare two datasets: poverty rate and bond number: Scatter plot or Group Bar chart.
Visualizing trend
To visualize and see trends over 20 years of data, I experimented these different options.
Test different options of charts to visualize trends: Sanky chart or Group Bar chart.
generate Insihgts
To make the data insights more accessible, I also explored these 2 ways of showing insights.
