Tips for incorporating data directly within a D3 bullet chart

Within the provided example, the code is utilizing d3.json to fetch data from a local file called "bullets.json" and passing it as 'data' to a callback function for further action.

I am looking to modify this process so that instead of fetching data from an external source, I can utilize a variable that has already been defined. This is because the web viewer in my application lacks access to the local file system.

Upon further consideration:

How can I effectively incorporate the 'dataset' variable into the script that generates a bullet chart using the data? Simply using d3.select() won't suffice in this scenario, as the SVG object needs to be created beforehand to attach the title.

var dataset = {"title":"Sales","subtitle":"£, 000","ranges":[50,200,400],"measures":[100,500],"markers":[250]};

d3.json("bullets.json", function(data) {
 var svg = d3.select("body").selectAll("svg")
  .data(data)
  .enter().append("svg")

Answer №1

Instead of fetching data from an external source, you can directly insert the variable that contains the data into the elements declaration for plotting multiple rectangles as shown below:

d3.selectAll('rect')
  .data([YourVariable]) //if the variable is already an array, no need for []
  .enter()
  .append('rect')
  .... etc.

I trust this explanation will be beneficial to you!
