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
