# D3 Base Component

Integrate React Lifecyle methods with d3.js charts.

## Base Component Responsibilities

- Create and manage mounting and unmounting parent `div` and `svg`
- Handle resize events, resulting re-renders, and event listeners
- Handle re-renders as a result of new props

## Props

### className

{ string } A class to be applied to the parent `div`

### getParams( node )

{ function } A function returning an object containing required properties for drawing a chart. This object is created before re-render, making it an ideal place for calculating scales and other props or user input based properties.

- `svg` { node } The parent `div`. Useful for calculating available widths

### drawChart( svg, params )

{ function } draw the chart

- `svg` { node } Base element
- `params` { Object } Properties created by the `getParams` function
