Introduction

Data science typically involves data, analysis, tests and outputs. A simple way to review, verify or present results is via Visualizations.

Plotly Dash is selected to help prepare and present visualizations in a single dashboard. The key is to help present results in a organized manner to avoid

Summary

A library is under development to standardize this. See dashhtmlgrid

#TODO

• A decidated plotly visualization library is required to help develop faster custom plotting
  • The data provided to charts should be dedicated dfs with simple configuration files

Usage

• Prepare data

• Define html div matrix using app layout (based on expected outputs). Some examples are:

• Utilize standard elements to plug into each matrix divs charts, tables

The library currently supports:

• 1 dropdown menu box (with only 1 input field)
• multiple tables
• multiple plots

Example codes

• Dropdown, multiple option selection. Example is given below:

Code file: src\dashhtmlgrid\tests\test_dropdown_multiple_options.py

• Dropdown - Single selection. Example is given below:
