CQUCOVID

---

COVID-19 Data Visualization

How to run

1. cd into root
2. run python -m pip install -r requirements.txt
3. runflask run or py app.py

Note: this will start flask in your local machine with debug mode: off , default URL is http://127.0.0.1:5000/.

Note: when using flask run, we are actually directly booting the server, which is the cqu_covid package. To boot with specific config, you can use py app.py to use custom python script to run the app. However, we recommend that build the config in __init__.py.

Package

The application is currently packed as a package cqu_covid. To import this package, pleause use from from cqu_covid import app , the file tree is :

├─cqu_covid
│  ├─static
│  ├─templates
│  └─`__init__.py`
└─`app.py`

1. Noticed that there's a loop import between __init__.py and views.py , this is fine in flask, but not recommended in python. Please see https://dormousehole.readthedocs.io/en/latest/patterns/packages.html

Data Interface

Kindly search TODO Data in views.py, and you will locate the position where data interfaces are needed.

We need 3 interfaces currently(2020/7/1), please check the corresponding static sample data for specific format.

Riino advices to use external package to generate data interface, this will help decrease the lines in views.py. To check bing-like page, please start serve and visit http://127.0.0.1:5000/home

Note that the type of pyechart is different : in index page, we use Map, in home page, we use Bio, and in home page’s country list, we use dictionary. See http://gallery.pyecharts.org/#/Geo/geo_base for more info.
