Modifying the color of specific sections of SVG elements

Interested in utilizing the d3.js timeknots component, a svg visualization that includes line and circle elements. My goal is to implement a stopwatch animation that dynamically changes the color of the svg visualization over time.

I am contemplating creating a duplicate version of the visualization with different colors, overlaying it on the original and manipulating the clipping of the colored copy incrementally. I am open to suggestions on whether this method is optimal or if there are alternative approaches available.

Answer №1

linearGradient is the perfect solution for this particular scenario.

<svg class="timeline" width="809" height="150">
   <defs>
      <linearGradient id="gradient" gradientUnits="userSpaceOnUse" y1="0px" y2="0px" x1="232" x2="233">
         <stop stop-color="#1689fb"></stop>
         <stop stop-color="rgb(126, 126, 126)"></stop>
      </linearGradient>
   </defs>
   <g stroke="url(#gradient)" class="wrapper-timeline">
      <g clip-path="url(#clipLine)" class="wrapper-lines">
         <line class="timeline-line" x1="11" x2="798" y1="75" y2="75" style="stroke-width: 2;"></line>
         <line class="timeline-line" x1="798" x2="798" y1="75" y2="75" style="stroke-width: 2;"></line>
      </g>
      <circle class="timeline-event" id="knot-0" r="6" cy="75" cx="11" style="stroke-width: 2; fill: rgba(220, 220, 220, 0.01);"></circle>
      <circle class="timeline-event" id="knot-1" r="6" cy="75" cx="798" style="stroke-width: 2; fill: rgba(220, 220, 220, 0.01);"></circle>
   </g>
   <use xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href=""></use>
   <text class="current-time" x="0" y="97" style="font-size: 70%;">00:20:03</text>
   <text class="duration" x="770.859375" y="97" style="font-size: 70%;">01:11:24</text>
</svg>
