Hello,
I am new to D3.js and I had trouble laying two SVG Treemaps on one page.
I got a hint from this.
What I want to do is lay two zoomable treemap elements on one page. (The sample above is for one treemap.)
I implemented the code myself, but not working properly.
Please help me if you are familiar with SVG and have experience with the zoomable D3 treemap.
chart1.js
fetch('../data/chart1.json')
.then((response) => response.json())
.then((json) => {
render(json, 'investicija');
render(json, 'proizvod');
})
.catch((error) => console.error('Error fetching data:', error));
function render(treemapData, selector) {
const renderData = treemapData[selector][0]; // Ensure this key exists in your JSON data
(function () {
const margin = { top: 20, right: 0, bottom: 0, left: 0 };
const container = document.getElementById(selector);
const width = container.clientWidth;
const height = container.clientHeight;
let svg, grandparent, scaleX, scaleY, treemap;
function createSvg() {
scaleX = d3.scale.linear()
.domain([0, width])
.range([0, width]);
scaleY = d3.scale.linear()
.domain([0, height])
.range([0, height]);
treemap = d3.layout.treemap()
.children((d, depth) => depth ? null : d._children)
.sort((a, b) => a.amount - b.amount)
.ratio(height / width * 0.5 * (1 + Math.sqrt(5)))
.round(false)
.value(d => d.value);
svg = d3.select(`#${selector}`).append("svg")
.attr("width", width + margin.left + margin.right)
.attr("height", height + margin.bottom + margin.top)
.style("margin-left", -margin.left + "px")
.style("margin-right", -margin.right + "px")
.append("g")
.attr("transform", `translate(${margin.left},${margin.top})`)
.style("shape-rendering", "geometricPrecision");
grandparent = svg.append("g")
.attr("class", "grandparent");
grandparent.append("rect")
.attr("y", -margin.top)
.attr("width", width)
.attr("height", margin.top + 10);
grandparent.append("text")
.attr("x", 25)
.attr("y", 6 - margin.top + 3)
.attr("dy", ".75em");
}
function initialize(d) {
d.x = d.y = 0;
d.dx = width;
d.dy = height;
d.depth = 0;
}
function accumulate(d) {
return (d._children = d.children) ? d.amount = d.children.reduce((p, v) => p + accumulate(v), 0) : d.amount;
}
function layout(d) {
if (d._children) {
treemap.nodes({ _children: d._children });
d._children.forEach(c => {
c.x = d.x + c.x * d.dx;
c.y = d.y + c.y * d.dy;
c.dx *= d.dx;
c.dy *= d.dy;
c.parent = d;
});
}
}
