react-native-d3-tree-graph

An implementation of d3 graph to construct flow chart(d3 topological graph(tree)).

Latest version Release note

• Now images can be added in place of rectangles in all nodes.
• Annoying issue with the previous version was collision between react-native-svg versions and it's resolved now.
• New props are available to style node which will be included along with node object like below.

           name: "J",
           id: 12,
           imageUrl: { href: { uri: "https://facebook.github.io/react-native/docs/assets/favicon.png"}}, //new prop
           nodeImageStyle: { imageHeight: 60 , imageWidth: 60, opacity: 1 }, //new prop
           nodeTextStyle: { fontSize: 12 } //new prop
  }```
  

• Example is upgraded to latest version of react native i.e 0.59.9 and react-native-svg i.e 9.5.1

var root = {
    name: "",
    id: 1,
    hidden: true,
    children: [ {
            name: "Q",
            id: 16,
            no_parent: true

    }

var siblings = [{
    source: {
        id: 3,
        name: "C"
    },
    target: {
        id: 11,
        name: "K"
    }
 }]
 
export default class example extends Component {
  render() {
    return (
        <View style={styles.container}>
        <AwesomeHierarchyGraph
         root = {root}
         siblings = {siblings}
        />
       </View>
    );
  }

const styles = StyleSheet.create({
