Show Percentage In SVG Graphic

I am trying to show current vaccination-data from a CSV-File provided by local authorities as a progress-bar in style of a syringe. Depending on the percentage of vaccinated people

Solution 1:

Easier done with a green path-stroke and pathLength=100

A stroke-dasharray="78 100" then sets percentage

svg {
  width: 150px;
}

<script>
  function updatePercentage(v = 50) {
    document.querySelector("#ceringe").setAttribute("stroke-dasharray", v + " 100");
  }
</script>

<input type="range" min="0" max="100" oninput="updatePercentage(this.value)">
<br>
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 512 512">
  <path id="ceringe" stroke-dasharray="50 100" pathLength="100" d="M108 403L380 132" 
        stroke="green" stroke-width="130" />

Solution 2:

I would recommend adding a clipping mask and then altering the width of the clipping mask with JS based on the values in the CSV file. This example shows have the icon in green and the full icon in black. If you change 0.5512 to 0.1512, it would be 10% full, etc.

let clipping = document.getElementById("clipping-rectangle")
clipping.width.baseVal.value = 0.5 * 512;

#container {
  margin: 20px;
  width: 200px;
  height: 200px;
}
