To create a single bar with a 3D effect in D3.js, you can add depth to the bar by creating additional rectangles to represent the top and right sides of the bar. Here's a step-by-step guide on how to achieve this:
- Define the data for the bar:
1
|
let data = [10]; // Single number representing the height of the bar |
- Create an SVG element to contain the bar:
1 2 3 4 |
let svg = d3.select("body")
.append("svg")
.attr("width", 200)
.attr("height", 200);
|
- Create the main rectangle for the bar:
1 2 3 4 5 6 7 8 9 |
svg.selectAll("rect")
.data(data)
.enter()
.append("rect")
.attr("x", 50)
.attr("y", 50)
.attr("width", 50)
.attr("height", d => d * 10) // Change the multiplier to adjust the height of the bar
.style("fill", "blue");
|
- Create the top side of the bar:
1 2 3 4 5 6 7 8 9 10 |
svg.selectAll(".top-side")
.data(data)
.enter()
.append("rect")
.attr("class", "top-side")
.attr("x", 50)
.attr("y", 50)
.attr("width", 50)
.attr("height", 5) // Adjust the height of the top side rectangle
.style("fill", "darkblue");
|
- Create the right side of the bar:
1 2 3 4 5 6 7 8 9 10 |
svg.selectAll(".right-side")
.data(data)
.enter()
.append("rect")
.attr("class", "right-side")
.attr("x", 100)
.attr("y", 50)
.attr("width", 5) // Adjust the width of the right side rectangle
.attr("height", d => d * 10)
.style("fill", "lightblue");

By following these steps, you should be able to create a single bar with a 3D effect in D3.js. Feel free to adjust the dimensions and colors of the rectangles to customize the appearance of the bar.
