Fun data visualization that creatively uses color

ColorEx Library

ColorEx is a data visualization and summarization library that uses color creatively to represent data, make visualization interactive, and ultimately be a great tool for learning patterns in data. It is meant to be simple, easy, and straight-forward.

Features

• Supports CSV data files for input.
• Generates and outputs color grid in HTML format.
• Themes supported both in-built and user-defined.
• Templates supported both in-built and user-defined.

Requirements

• Python 3.7+
• Cheetah

Installation

Install using pip (recommended)

To begin using the ColorEx library, we first install it using pip.

(NOTE: You'll need an Internet connection for this one!)

$ pip install colorexlib

Let's Get Started

Your first program!

Let's get started with your first python program using the ColorEx library.

1. Create a new directory on your computer.
2. Copy and paste the following code into a new file and save it as first_colorex.py, in in your directory.

# import modules 
from colorexlib.colorex import ColorExGrid

# set tile grid options
options = dict()
options['source'] = ['attendance.csv', 'csv']
options['title'] = 'Student Attendance'
options['subtitle'] = 'Attendance of students per month in 2018'
options['theme'] = 'sun.cxt'

# create ColorEx object, passing options.
colorex_grid = ColorExGrid(options)

# create color grid in HTML
colorex_grid.to_html('attendance.html','template.html')

3. In this repository, download the files attendance.csv and template.html in the first_examples directory and move them into the directory you created in step (1).

4. Now you should have three files (3) in the same directory:

   1. first_colorex.py,
   2. attendance.csv and
   3. template.html.

   Let's carry on!

5. Now open and run your python script first_colorex.py.

6. If all things go smoothly, a new HTML file called attendance.html will be created in the same directory.

7. Open this new HTML file, and you will see a color grid quite similar to the one shown below:

Yayyy! So you've completed your first ever ColorEx script. Pretty simple right?!

Examples

One of the best ways of learning how to use ColorEx is by looking at and studying a couple of examples. We've got you covered in this area. In this repo, navigate to the examples directory. You will notice a few examples that will help you achieve a solid understanding of how things work, along with the required CSV data files, templates, and theme files too.
