How to Add Html Special Character In D3.js?

In order to add HTML special characters in D3.js, you can use the "text()" function to set the inner HTML of an element. This function can be used to add special characters like "&", "<", ">", etc. by specifying their corresponding HTML entities or Unicode characters. You can also directly paste the special character codes in the text function to display them in your D3.js visualization. Remember to encode special characters properly to ensure that they are displayed correctly in the output.

// Alternatively, you can use the yen symbol directly in your data
var data = [
    { currency: "¥100" },
    { currency: "¥200" },
    { currency: "¥300" }
];

// Bind data to text elements
var text = svg.selectAll("text")

    .attr("x", function(d, i) { return i * 100; })
    .attr("y", 100)
    .text(function(d) { return d.currency; });

In the above example, we first append a text element to the SVG and use the Unicode character for the yen symbol "\u00A5". Alternatively, you can include the yen symbol directly in the data and display it in the text elements.
