    University Ranking by Overall Score

    This assignment was my first exposure to Javascript d3 library. The task was to design and develop a visualization related to university data. I merged data from Times Higher Education World University Ranking and Forbes' America's Top Colleges to compare American university rankings. The first visualization compares the rankings based on overall score of the universities from both sources. This visualization has been selected by the Information Visualization course professor at School of Information, University of Michigan as a reference for students for at least 3 semesters.

    University Ranking by Category

    This visualization compares American university rankings from various aspects including tuition cost, student population, teaching, international outlook, research, citations, student satisfaction, post-graduation successs, student debt, graduation rate and nationally competitive awards. The sources are from Times Higher Education World University Ranking and Forbes' America's Top Colleges. The main reason two sources were used is to view the rankings from the univerity perspective and students perspective. This visualization has been selected by the Information Visualization course professor at School of Information, University of Michigan as a reference for students for at least 3 semesters.

    UMSI Courses

    A final project for the Information Visualization course. We decided to use course enrollment data of our school (UMSI) to build a visualization related to specializations offered in the school's graduate program. The visualization also involves some behind-the-scene steps in data processsing using Python. The visualization itself is built using HTML5 with Javascript d3 and JQuery Library.

    Locomotive Tracking

    Locomotive Tracking

    A side project to visualize tabular data into graphical representations to analyze and to understand train's locomotive data. This visualization shows the start and end stations of the locomotive for the partcular train with indication of the lead locomotive. The objective of this visualization is to analyze the quality of the locomotive data in terms of whether every station has a reported locomotive for the train and has a lead locomotive.
