Architecture and design

Stage goals

The main goal of this stage is to prepare an initial proposal on:

1. Modules that the application should consist of
2. Communication between modules

List of modules

When performing software design activities for this project, please, keep in mind the following modules:

Name	Description
Dataset management	Module thats responsible for adding/removing x/y points
Chart	DOM-based dataset representation
Features	Set of features that can be applied to a dataset

General requirements and constraints

1. Pure Javascript, no frameworks or helper libraries (e.g lodash, jQuery)
2. No asset bundling (e.g no Webpack)
3. No CSS pre/post processing
4. No adaptive optimizations required

Dataset management requirements and contsraints

1. User should be able to:

   • Add a pair of points to a dataset
   • Remove a pair of points from dataset
   • Clear dataset

2. Dataset series should follow the interface:

   {
     "x":[5,16,20],
     "y":[63,66,68]
   }

3. Dataset should have the ability to be loaded from external data source (AJAX or any other) as well as ability to save its contents to an external storage (AJAX/WebStorage).

Chart requirements and contstraints

1. Chart dimensions are 500x500 pixels
2. Chart should be implemented using DOM-objects (no SVG or 2D canvas as well as any helper libraries)
3. No need to connect the dots on chart (although, doing so would be a plus)
4. Chart grid is optional.

Reference materials

1. Software design with SOLID
2. JS module pattern
3. OOP in JS
4. Closures
5. Intro to MVC
