UBC Grades - Dash

Building off of the original incredible ubcgrades.com project, I am utilizing Plotly's Dash system to analyze and visualize UBC grade data with less code.

Data sources

From the ubcgrades.com API, I can receive grades distributions as json objects, then transform them into dataframes for python and plotly to manage.

For example https://ubcgrades.com/api/v3/grades/UBCV/2022S

Docker-dash

Instructions from docker-dash...

Build and run

prod version is served by gunicorn instead of the flask dev server.

# dev
docker build -f Dockerfile.dev -t ubcdash-dev .
docker run -p 8050:8050 -v "$(pwd)"/app:/app --rm ubcdash-dev

# prod
docker build -f Dockerfile -t ubcdash-prod .
docker run -p 8050:8050 -v "$(pwd)"/app:/app --rm ubcdash-prod

Access the page

Go to http://localhost:8050 in browser.

Switch debug mode in Dockerfile

ENV DASH_DEBUG_MODE True # False

Development

Install the app requirements for development to get better editor support.

poetry install

Optional: clean initialization of poetry:

poetry init
cat app/requirements.txt | xargs poetry add

Playground jupyter notebook

see my playground jupyter notebook for current progress

Future developments

• tidy up imports with requirements.txt
• create a dash app mvp
• showcase sample plotly charts in screenshots
• refine openai outputs
• create dash app with charts that match what is currently on ubcgrades.com
• find/make a chatgpt interface on dash
• improve markdown on ipynb file
• separate out helper functions
• improve UI of charts
• host application and database and functions on the cloud. Ex: GCP Cloud Run, Cloud Store, Cloud Functions. Or Render.com. Docker image would be great too.

Curent priorities

• filter dropdowns
• show "OVERALL" section by defaul
• year x axis only has 3 options 2021, 2022, 2023. Not 2021.5
• capitalize labels (axis, legend)
• give larger marker to the "OVERALL" vs the sections - not sure if this is possible (conditional markers)

Questions I'd like to be able to answer

• SELECT campus, subject, course where average > 90
• questions: what courses in 3rd and 4th year can I take that have the highest average?
• what courses have the lowest fail rate? (<50 or <55%)
• how do grades compare between sections of the same class?
• how do grades compare between profs over the years/classes?
• does class size influence grades?
• what subjects (CPSC, MATH, etc) have the highest averages?
• what MATH 1xx courses have the highest and lowest averages?
