# [◀ Excalidraw Automate How To](../readme.md)
|
|
## Mindmap from Tasklist using dataviewjs
|
|
This is similar to the mindmap script using templater, but because dataview already returns tasks in a tree, it is slightly simpler
|
|
|
|
### Output
|
|
|
|
|
|
### Input file
|
|
The input file is `Demo.md` with the following contents:
|
|
```markdown
|
|
- [ ] Root task
|
|
- [ ] task 1.1
|
|
- [ ] task 1.2
|
|
- [ ] task 1.2.1
|
|
- [ ] task 1.2.2
|
|
- [ ] task 1.3
|
|
- [ ] task 1.3.1
|
|
```
|
|
|
|
### dataviewjs script
|
|
The `dataviewjs` script looks like this:
|
|
*Use <kbd>CTRL+Shift+V</kbd> to paste code into Obsidian!*
|
|
```javascript
|
|
function crawl(subtasks) {
|
|
let size = subtasks.length > 0 ? 0 : 1; //if no children then a leaf with size 1
|
|
for (let task of subtasks) {
|
|
task["size"] = crawl(task.subtasks);
|
|
size += task.size;
|
|
}
|
|
return size;
|
|
}
|
|
|
|
const tasks = dv.page("Demo.md").file.tasks[0];
|
|
tasks["size"] = crawl(tasks.subtasks);
|
|
|
|
const width = 300;
|
|
const height = 100;
|
|
const ea = ExcalidrawAutomate;
|
|
ea.reset();
|
|
|
|
function buildMindmap(subtasks, depth, offset, parentObjectID) {
|
|
if (subtasks.length == 0) return;
|
|
for (let task of subtasks) {
|
|
if (depth == 1) ea.style.strokeColor = '#'+(Math.random()*0xFFFFFF<<0).toString(16).padStart(6,"0");
|
|
task["objectID"] = ea.addText(depth*width,(task.size/2+offset)*height,task.text,{box:true})
|
|
ea.connectObjects(parentObjectID,"right",task.objectID,"left",{startArrowHead: 'dot'});
|
|
buildMindmap(task.subtasks, depth+1,offset,task.objectID);
|
|
offset += task.size;
|
|
}
|
|
}
|
|
|
|
tasks["objectID"] = ea.addText(0,(tasks.size/2)*height,tasks.text,{box:true});
|
|
buildMindmap(tasks.subtasks, 1, 0, tasks.objectID);
|
|
|
|
ea.createSVG().then((svg)=>dv.span(svg.outerHTML));
|
|
