Then it becomes a graph data structure, and you can use different layout methods like Sugiyama layered graph drawing, or even force layout! Do you have specific data in mind?
The data structure in memory that you pass in does need to be a specific structure. However, if you have "normal" json, you can write code to transform that into the tree data structure expected, or use d3.stratify if it's a list of things with parent-child relationships.
Hey Curran, thanks for these wonderful tutorials. At 20:20, I think we're having to access data twice because our json data has a `data` attribute besides the `children` attribute. Correct me if I am wrong but what I am picking is that d3.hierarchy will collect every attribute that is in the same level as the `children` attribute in a node and pack it inside an attribute called `data` in the resultant hierarchy object; since our json nodes have `data` and `children` as the attributes, d3.hierarchy expectedly collects the `data` attribute and packs it inside an attribute `data` in the resultant hierarchy.
Plz try to edit each node text . and try to data get from database not JSON ..plz help me.. I tried.. when i get value from table and edit all nodes..edited value easily edit but not show edited value in current time ...edited value show whren we refresh node
Very nice Curren! Do we have any solution to prepare the json file automatically based on the excel file data. If we provide any set of data, json file should change accordingly ?
Yes. Dynamic how? Change data input --> tree updates. Use transitions for visual animation effect. Operations on trees: open/close nodes, change node values, add/remove nodes.
Guys if your lowest depth did not load keep watching! Nothing wrong with code! Also put your JS inside of the body!
You're good at teaching d3, thanks a lot for sharing your knowledge
Hey can you please make a video for the radial
Thanks for the video.The code in github is not working. Getting blank page and bundle.js file is also missing
Did you run npm install and npm run build?
any chance to have polyheirarchical structure

Super! Thank You Curran.
it does not support a normal json structure it need to be a particular structure to execute

Very helpful! Thank you :)
Looks great, thanks.
Hey Curran, can you please share the link for radial tree video ?
There's no video for it, but here's the original radial tree blocks.roadtolarissa.com/curran/1dd7ab046a4ed32380b21e81a38447aa
Nice .. how to make it collapsible?
Can I have a link to the original circular graph pls?
Here is the circular version: vizhub.com/curran/c06d039880c440558c47a7cb20c3fcd1

Yes that sounds right.

Do we have any solution to prepare the json file automatically based on the excel file data. If we provide any set of data, json file should change accordingly ?
You can export from Excel to CSV, then load the CSV data using d3.csv. For trees, you can convert from CSV to nested JSON using d3.stratify
Here's the underlying preprocessing github.com/curran/data/tree/gh-pages/un/placeHierarchy
Hey, can we make it dynamic?
Yes. Dynamic how? Change data input --> tree updates. Use transitions for visual animation effect. Operations on trees: open/close nodes, change node values, add/remove nodes.
You would use react js as a Main Wrapper and pass the data from state from apis
Thanks!
best one
Thank you
NO LIMIT WITH LIMITLESS DATA
Plz tell me how to edit this nodes text edit?
Try putting an "input" element in the SVG using "foreignObject".
Plz make a video for edit nodes with database plzz
