How can I integrate JSON visualization in my web app?

You can use libraries like D3.js or Chart.js to visualize JSON data in your web app. Would you like a code example?

Yes, please provide a code example using D3.js.

Sure! First, include the D3.js library in your HTML. Then, you can use the following code to visualize your JSON data:

const data = [
  { "name": "A", "value": 30 },
  { "name": "B", "value": 80 },
  { "name": "C", "value": 45 }
];

const svg = d3.select('svg');
const circles = svg.selectAll('circle')
  .data(data)
  .enter()
  .append('circle')
  .attr('cx', (d, i) => (i + 1) * 50)
  .attr('cy', 50)
  .attr('r', d => d.value);

This will create circles based on the values in your JSON.

What if I want to create a bar chart instead?

You can modify the code to create a bar chart by using rectangles instead of circles. Here's an example:

const svg = d3.select('svg');
const bars = svg.selectAll('rect')
  .data(data)
  .enter()
  .append('rect')
  .attr('x', (d, i) => (i + 1) * 60)
  .attr('y', d => 100 - d.value)
  .attr('width', 50)
  .attr('height', d => d.value);

This will create a bar chart representing your JSON data.
