A basic D3 plugin that interpolates though the HUSL and HUSLp color space. For now, the interpolator accepts hex or hsl strings, i.e. #f00, #ff0000 or hsl(0, 100%, 50%)

npm install d3-interpolate-husl

Alternatively, the good old <script> still works with d3-interpolate-husl.js or d3-interpolate-husl.min.js.
