react-gauge-component

React Gauge Chart Component for data visualization.

This is forked from @Martin36/react-gauge-chart 0b24a45. Key differences:

• Added min/max values
• Added arcs limits in value instead of percent
• Added inner/outer marks to the gauge for reference of the values
• More than one gauge type
• More than one pointer type
• Added tooltips on hover for the arcs
• Added arc with linear gradient colors
• Full responsive
• All render flow fixed and optimized avoiding unecessary resource usage (better performance)
• Refactored project structure to separated files
• Refactored to Typescript
• Added complex objects for better modulation and organization of the project
• Fixed Rerenderings making arcs to be repeated in different sizes
• Fixed needing to set height bug
• Fixed needing to set id bug

##### Colors for the chart

The 'colorArray' prop could either be specified as an array of hex color values, such as ["#FF0000", "#00FF00", "#0000FF"] where each arc would a color in the array (colors are assigned from left to right). If that is the case, then the length of the array must match the number of levels in the arc. If the number of colors does not match the number of levels, then the first and the last color from the colors array will be selected and the arcs will get colors that are interpolated between those. The interpolation is done using d3.interpolateHsl.
