I'm currently working on a project involving the creation of a Force-Directed Graph using D3.js version 6. When users interact with nodes by clicking on them, a context menu should appear. This menu should disappear when users click elsewhere in the SVG. Here's an example:
No context menu

With context menu

Everything functions as expected so far. Now, I want to incorporate transitions for creating and deleting the context menu using d3.easeCircleIn and d3.easeCircleOut from the d3-ease library.
To set up the context menu, I am utilizing a donut chart with static data. The code snippet is shown below:
// Context menu data
const contextMenu = [
{
value: 1,
type: 'unlock',
icon: require('@/assets/images/unlock.svg'),
text: 'Unlock the node to re-layout the graph'
},
{
value: 1,
type: 'info',
icon: require('@/assets/images/info.svg'),
text: 'Show node detailed information'
}
];
const pie = d3.pie()
.value((d: any) => d.value)
.padAngle(0.0349066); // 2 degrees in radian
this._donutData = pie(contextMenu);
this._arcGenerator = d3.arc()
.innerRadius(this._options.nodeRadius * 1.35)
.outerRadius(this._options.nodeRadius * 2.5)
Upon the click event of a node, I call the createDonut function to generate the donut chart:
private createDonut(node: any) {
const _me = this;
return node.selectAll('arc')
.data(this._donutData)
.enter()
.append('path')
.attr('class', this._arcClass)
.attr('d', this._arcGenerator)
.attr('fill', '#eeeeee')
.style('opacity', 0.7)
.on('click', function (event: any, chosenArc: any) {
// Remove other context menus
d3.select(`.${ _me._contextMenuClass }`).remove();
// Further actions...
});
}
Now, I want to integrate d3-transition into this process. However, simply adding .transition() after the click event does not have the desired effect. The same problem occurs during deletion.
// Transition not functioning
d3.select(`.${ _me._contextMenuClass }`)
.transition()
// Define transition parameters...
.remove();
If anyone could provide guidance on how to successfully implement transitions for the context menu, it would be greatly appreciated. Thank you!
