For d3, given an array of nested objects. Is it possible to only render a certain amount of depth?
I am basing off of some sunburst examples online like : https://github.com/Nikhilkoneru/react-d3-zoomable-sunburst/blob/master/src/index.js
Using the .selectAll method from d3, can I only limit the sunburst to render 'X' depths, instead of rendering the entire array of nested objects?
I'm trying to render a really large array, and it causes a really laggy experience.
This is the selectAll that I'm using from the github example.
svg.selectAll('path')
.data(partition(root)
.descendants())
.enter()
.append('path')
.style('fill', (d) => {
let hue;
const current = d;
if (current.depth === 0) {
return '#33cccc';
}
if (current.depth <= 1) {
hue = hueDXScale(d.x0);
current.fill = d3.hsl(hue, 0.5, 0.6);
return current.fill;
}
if(current.depth <= 2){
console.log("depth > 2: ", d)
current.fill = current.parent.fill.brighter(0.5);
const hsl = d3.hsl(current.fill);
hue = hueDXScale(current.x0);
const colorshift = hsl.h + (hue / 4);
return d3.hsl(colorshift, hsl.s, hsl.l);
}
})
.attr('stroke', '#fff')
.attr('stroke-width', '1')
.on('click', d => click(d, node, svg, x, y, radius, arc))
.on('mouseover', function (d) {
if (props.tooltip) {
d3.select(this).style('cursor', 'pointer');
tooltip.html(() => {
const name = utils.formatNameTooltip(d);
return name;
});
return tooltip.transition().duration(50).style('opacity', 1);
}
return null;
})
.on('mousemove', () => {
if (props.tooltip) {
tooltip
.style('top', `${d3.event.pageY - 50}px`)
.style('left', `${props.tooltipPosition === 'right' ? d3.event.pageX - 100 : d3.event.pageX - 50}px`);
}
return null;
})
.on('mouseout', function () {
if (props.tooltip) {
d3.select(this).style('cursor', 'default');
tooltip.transition().duration(50).style('opacity', 0);
}
return null;
});
As you can see, from the current.depth, i'm able to filter out what depth is more than 2. Is it possible to add display: none to anything more than depth of 2, or is there a better way to not render anything more than depth of 2 from current
