Bar Loader (Equalizer)

A row of dots bounce, fade or scale in sequence.

Add "Bouncing Dots" (also called a dots loader or three-dot loader) to [where].
The dots should hop up and land one after another in a light, springy rhythm, with a short rest before the sequence repeats.
Keep the loop seamless, give it a status label for screen readers, and stop the motion for users who prefer reduced motion.

Bars rise from zero height to their data values.

Add a "Bar Chart Grow" animation (also called an animated bar chart or bar chart entrance) to [where].
Each bar should rise from the baseline to its value one after another in a quick stagger, easing out smoothly as it settles.
Play it once when the chart comes into view, and show the finished chart right away to users who prefer reduced motion.

Chart elements interpolate smoothly from old to new values when data changes or datasets toggle.

Add a "Chart Data Transition" (also called a chart update animation) to [where].
When the data changes, every bar should glide from its old value to its new one at the same time, smooth and unhurried, instead of redrawing from zero.
Start each update from the values currently on screen so a quick second change does not jump, and apply new values instantly for users who prefer reduced motion.

A tiny blurred version of an image sits in place and sharpens as the full image loads.

Add a "Blur-Up Placeholder" image loading effect (also called LQIP or a blur placeholder) to [where].
A tiny, heavily blurred version of the image should fill the image's space right away, and once the full image has loaded it should sharpen into place smoothly and fairly quickly.
Reserve the image's exact size so nothing shifts when it arrives, and clip the blurred edges so they do not bleed past the frame.

A button swaps its label for, or adds, a small spinner while an action runs.

Add a "Button Loading State" (also called a spinner button or loading button) to [where].
When pressed, the button should give a small press, fade its label out and show a small spinner in its place while the action runs, then bring the label back when it finishes.
Keep the button's width fixed while it loads, block repeat presses, and announce the busy state to screen readers.
