Create semicircular gauge charts for KPI dashboards with custom ranges, colors, and needle animation.
Build a semicircular KPI dial by defining the scale, dividing it into colored ranges, and setting the value indicated by the needle. The result suits a dashboard tile where viewers need a quick status reading rather than a dense time series. Needle animation can emphasize the current reading as the chart appears. The frequent mistake is treating range colors as self-explanatory: a red, amber, or green segment has no fixed meaning unless the dashboard identifies the metric, unit, target, and direction of improvement.
Set the numeric span that the semicircle represents, then divide that span into colored intervals. The current KPI value is located against the same span, and the needle gives its position while the arc gives its status context. Keep endpoints in ascending order and make adjacent boundaries explicit, because the visual cannot resolve an intended gap, overlap, or reversed interval for the reader.
Choose a value within the displayed scale and use animation when motion helps viewers notice the final needle position. The animation does not add another measurement; it only changes how the selected reading is introduced. Pair the dial with a written value and unit so users can recover the exact figure instead of estimating it from the needle angle.
No. Its stated chart form is a semicircular gauge. A full 360-degree dial, radial progress ring, or multi-needle instrument is a different chart specification and should not be inferred from this output. Use this generator when one value needs a half-dial presentation with colored status ranges and an animated needle.
No. Needle animation presents the configured reading; it does not establish a data feed, refresh schedule, timestamp, or historical record. If the gauge appears in a live dashboard, those behaviors must be supplied and explained by the surrounding dashboard. Treat the motion as presentation, not evidence that the value is current.
