  render() {
    return (
      ...
      <Cloud keywords={keywordsArray} scale={250} largestAtCenter={true} drawContainerCircle={true} containerCircleColor={'#345678'}/>

API

Props

• keywords : array of keyword objects. Each keyword object should be of type

    {
        keyword: "word1",    // the actual keyword
        frequency: 123,      // the frequency of this keyword
        color: "#121234"     // the color of the circle that shows this keyword
    }

• scale : number which determines the scaling of the circles. Play around with it to find out which value gives you the size you need. Defaults to 250

• largestAtCenter : boolean which determines whether the largest circles should be concentrated towards the center of the cloud or vice versa. Defaults to true

• drawContainerCircle : boolean which determines whether or not to draw a container circle around the word cloud. Defaults to false

• containerCircleColor : fill color for the container circle. Defaults to '#FF000030'
