dash

The Covid data visualization dashboard is one of UTA ITLab's research projects, focusing on multilayer network analysis. This web application showcases graph visualization techniques in two ways; a choropleth map shows changes in statistics across time, and a side-by-side line graph is used to compare statistics from various regions over a similar time period.

Local development

Clone this repository

$ git clone https://github.com/ITLab-research/cowiz-bangkok-dashboard
$ cd cowiz-bangkok-dashboard	

Create python virtual environment and install required packages:

$ python3 -m virtualenv venv
$ source venv/bin/activate
$ pip install -r requirements.txt

The app requires a New York Times API key in .env; e.g. NYTAPI_KEY=<api key>

Compile the csvGenerator:

$ g++ -o cowiz/usmap/csvLayers/csvGenerator cowiz/usmap/csvLayers/csvGenerator.cpp

Set the development flask environment variables:

$ export FLASK_APP=cowiz
$ export FLASK_ENV=development

To skip from having to set environment variables every time you activate venv, add the following lines to venv/bin/activate:

    ...
    
    # reset old environment variables
    # INSERT BELOW
    if ! [ -z "${_OLD_FLASK_APP:+_}" ] ; then
        FLASK_APP="$_OLD_FLASK_APP"
        export FLASK_APP
        unset _OLD_FLASK_APP
    fi
    if ! [ -z "${_OLD_FLASK_ENV:+_}" ] ; then
        FLASK_ENV="$_OLD_FLASK_ENV"
        export FLASK_ENV
        unset _OLD_FLASK_ENV
    fi
    # DONE INSERTING
    
    ...
    
export VIRTUAL_ENV

# INSERT BELOW
_OLD_FLASK_APP="$FLASK_APP"
FLASK_APP=cowiz
export FLASK_APP

_OLD_FLASK_ENV="$FLASK_ENV"
FLASK_ENV=development
export FLASK_ENV
# DONE INSERTING

Run the app:

$ flask run
