Expand nodes dynamically

[mayukhghoshme]

Hi,
I am new to this and evaluating react-d3-graph for a project. Below is my question:

• Is there a way I can populate a node dynamically?
• For example, if I have a parent node and 3 children associated with it, can I click on the child nodes, fetch the data from db and append to the child node its children, thus showing a grandparent to grandchildren relationship?

Yes, you can achieve this feature. You can try with the below steps:

• Maintain the data in a state variable.
• Handle click event of the nodes.
• Update the latest data from DB with setState of the data variable and once that's done you can able to see the new nodes.
• For merging the data I used one package and ie. deepmerge. You can use direct JavaScript. But above package can take care of any type of data format.
• Suppose if you updated the new data then you may use the old one. To bind the with previous data use the below syntax deepmerge(newData, graphData).
• You can follow the same for the remaining nodes also.
