How to arrange rectangles in rows in d3.js?

@scotty_walker 

To arrange rectangles in rows in d3.js, you can use the following steps:

1. Define the dataset that contains the information for each rectangle, such as its width, height, color, etc.
2. Create a SVG element to contain the rectangles.
3. Use the .selectAll() method to bind the dataset to rectangles.
4. Use the .enter() method to create a rectangle for each data point in the dataset.
5. Set the position and size of each rectangle based on its index in the dataset, such as its x and y coordinates and width and height.
6. Use a loop or a specific logic to arrange the rectangles in rows.

Here is a basic example of arranging rectangles in rows in d3.js:

// Define the dataset
var data = [30, 50, 70, 40, 60];

// Create a SVG element
var svg = d3.select("body")
            .append("svg")
            .attr("width", 500)
            .attr("height", 200);

// Bind the dataset to rectangles
var rects = svg.selectAll("rect")
               .data(data)
               .enter()
               .append("rect")
               .attr("x", function(d, i) { return i * 80; }) // Arrange rectangles in rows with a 80px padding
               .attr("y", 50)
               .attr("width", 50)
               .attr("height", function(d) { return d; })
               .attr("fill", "blue");

In this example, we have a dataset with 5 values, and we arrange the rectangles in rows with a padding of 80 pixels between each rectangle. You can modify the code to fit your specific requirements, such as adjusting the size and position of the rectangles or changing the spacing between rows.
