By the end, you’ll have the skills to visualize data beautifully and efficiently.

Why Use CSS for Pie Charts?

Using CSS for pie charts has several advantages:

  • Clean and Lightweight: CSS charts are lightweight and do not require additional libraries.
  • Customizable: You have complete control over styles such as colors, sizes, and animations.

Step-by-Step Guide to Create a Pie Chart in CSS

Step 1: Basic HTML Structure

Start by creating a simple HTML structure for your pie chart.

<div class="pie-chart"></div>

Step 2: CSS for the Pie Chart

Now, let’s style our pie chart using CSS. We’ll create a series of divs representing slices of the pie.

.pie-chart {
  width: 200px;
  height: 200px;
  border-radius: 50%;
  position: relative;
}
.slice {
  position: absolute;
  width: 50%;
  height: 100%;
  background-color: #3498db;
  transform-origin: 100%;
}
.slice:nth-child(1) {
  transform: rotate(0deg);
}
.slice:nth-child(2) {
  transform: rotate(90deg);
}
.slice:nth-child(3) {
  transform: rotate(180deg);
}

Step 3: Adding Pie Slices

To represent each data point, add more divs within the pie chart.

<div class="pie-chart">
  <div class="slice" style="background-color: #e74c3c; transform: rotate(0deg);"></div>
  <div class="slice" style="background-color: #f1c40f; transform: rotate(90deg);"></div>
  <div class="slice" style="background-color: #2ecc71; transform: rotate(180deg);"></div>
</div>

Step 4: Fine-Tuning Your Chart

You can further customize your pie chart by adding shadows, borders, and animations:

.pie-chart {
  box-shadow: 0 4px 8px rgba(0, 0, 0, 0.2);
}
.slice {
  transition: transform 0.3s ease;
}
.slice:hover {
  transform: scale(1.1);
}
