+# HorizontalScroller
+
+The `HorizontalScroller` component is helpful in making horizontal scrolling sections that respond to vertical scroll input. It is flexible in a way that it can horizontally scroll any children content wider than 100vw from one end to the other.
+
+To scroll any DOM layout wider than the viewport, wrap the content inside the `HorizontalScroller` component. The component will take care of the rest.
+
+## Basic demo
+
+To use the `HorizontalScroller` component, import it and provide the children content to scroll. The scroll height defaults to `200lvh`, but you can adjust this to any valid CSS height value such as `1200px` or `200lvh` with the `height` prop.
+
+> 💡TIP: Use `lvh` or `svh` units instead of `vh` unit for the height, as [these units](https://www.w3.org/TR/css-values-4/#large-viewport-size) are more reliable on mobile or other devices where elements such as the address bar toggle between being shown and hidden.
+
+[Demo](?path=/story/components-graphics-horizontalscroller--demo)
+
+```svelte
+<script lang="ts">
+  import { HorizontalScroller } from '@reuters-graphics/graphics-components';
+</script>
+
+<!-- Optionally set `height` to adjust scroll height -->
+<HorizontalScroller height="400lvh">
+  <div style="width: 200vw; height: 100lvh;">
+    <!-- Content wider than 100vw -->
+    <!-- Only the top 100lvh will be visible -->
+    <img
+      src="path/to/wide-image.jpg"
+      alt="alt text"
+      style="width: 100%; height: 100%; object-fit: cover; padding: 0; margin: 0;"
+    />
+  </div>
+</HorizontalScroller>
+```
+
+## With stops
+
+The `HorizontalScroller` also allows you to define a set of points to stop or slow down the scrolling at specific intervals using the `stops` prop. This is useful for creating step-based horizontal scrolling experiences.
+
+The `scrubbed` prop can be used to define whether the scrolling experience should be smooth or tied directly to the scroll position. Setting `scrubbed` to `true` will make the horizontal scroll position directly correspond to the vertical scroll position, while setting it to `false` will create a smooth scrolling effect.
+
+If `scrubbed` is set to `false` and `stops` are defined, the scroller will transition smoothly to the next stop when the scrollProgress reaches the midpoint between two stops. The transition speed is controlled by the `duration` prop (in milliseconds) and the `easing` prop (which accepts any easing function from `svelte/easing` or a custom function based on signature `(t: number) => number`).
+
+If `scrubbed` is set to `true` and `stops` are defined, all the stops are traversed at equal distance but based on the easing function provided.
+
+Feel free to toggle `scrubbed` prop here to see the difference.
+
+[Demo](?path=/story/components-graphics-horizontalscroller--demo)
+
+```svelte
+<script lang="ts">
+  import { HorizontalScroller } from '@reuters-graphics/graphics-components';
+  import { quartInOut } from 'svelte/easing';
+</script>
+
+<!-- Optionally set `height` to adjust scroll height -->
+<HorizontalScroller
+  height="200lvh"
+  stops={[0.2, 0.5, 0.6, 0.7]}
+  duration={400}
+  scrubbed={false}
+  easing={quartInOut}
+  showDebugInfo
+  direction="right"
+>
+  <div style="width: 200vw; height: 100lvh;">
+    <!-- Content wider than 100vw -->
+    <!-- Only the top 100lvh will be visible -->
+    <img
+      src="path/to/wide-image.jpg"
+      alt="alt text"
+      style="width: 100%; height: 100%; object-fit: cover; padding: 0; margin: 0;"
+    />
+  </div>
+</HorizontalScroller>
+```
+
+## With custom child components
+
+You can create a horizontal stack of any components and pass it as children to the `HorizontalScroller`. Here's an example of using `DatawrapperChart`, `Headline` and ai2svelte components inside the scroller.
+
+[Demo](?path=/story/components-graphics-horizontalscroller--custom-children)
+
+```svelte
+<script lang="ts">
+  import {
+    Block,
+    DatawrapperChart,
+    Headline,
+    HorizontalScroller,
+  } from '@reuters-graphics/graphics-components';
+  import AiChart from './ai2svelte/ai-chart.svelte';
+  import { quartInOut } from 'svelte/easing';
+</script>
+
+<HorizontalScroller
+  height="200lvh"
+  stops={[0.2, 0.5, 0.6, 0.7]}
+  duration={400}
+  scrubbed={false}
+  easing={quartInOut}
+  direction="right"
+  showDebugInfo
+>
+  <div id="horizontal-stack">
+    <div style="width: 100vw;">
+      <DatawrapperChart
+        title="Global abortion access"
+        ariaLabel="map"
+        id="abortion-rights-map"
+        src="https://graphics.reuters.com/USA-ABORTION/lgpdwggnwvo/media-embed.html"
+        frameTitle=""
+        scrolling="no"
+        textWidth="normal"
+        width="wider"
+      />
+    </div>
+    <div style="width: 100vw;">
+      <Headline
+        hed="Reuters Graphics Interactive"
+        dek="The beginning of a beautiful page"
+        section="World News"
+      />
+    </div>
+    <div style="width: 100vw;">
+      <Block width="normal">
+        <AiChart />
+      </Block>
+    </div>
+  </div>
+</HorizontalScroller>
+
+<style lang="scss">
+  #horizontal-stack {
+    display: flex;
+    flex-direction: row;
+    align-items: center;
+    justify-content: space-around;
+    gap: 10vw;
+    height: 100%;
+  }
+</style>
+```
+
+## With ai2svelte components
+
+With ai2svelte v1.0.3 onwards, you can export your ai2svelte graphic with a wider-than-viewport layout and use it directly inside the `HorizontalScroller` component to create horizontal scrolling graphics.
+
+To do that, follow these steps:
+
+1. In Illustrator, rename your artboard with a tag indicating breakpoint width for that artboard to be visible on page. For example, to make the XL artboard visible on viewports wider than 1200px, rename the artboard to `xl:1200`. You can have more than one artboard with different breakpoint widths.
+2. In ai2svelte settings, set these properties and run ai2svelte to export the component.
+
+```yaml
+include_resizer_css: false
+respect_height: true
+allow_overflow: true
+```
+
+This can be useful to even transition tagged content inside the ai2svelte graphic as part of the horizontal scrolling experience. For example, caption boxes exported as `htext` tagged layers can be animated to fade in/out or move in/out of view based on the scroll progress. Or one could even use tagged `png` layers to create parallax effects.
+
+[Demo](?path=/story/components-graphics-horizontalscroller--scrollable-ai-2-svelte)
+
+```svelte
+<script lang="ts">
+  import { HorizontalScroller } from '@reuters-graphics/graphics-components';
+  import AiGraphic from './ai2svelte/ai-graphic.svelte';
+  import { sineInOut } from 'svelte/easing';
+
+  // bind scrollProgress for advanced interactivity
+  let scrollProgress: number = $state(0);
+</script>
+
+<HorizontalScroller
+  width="fluid"
+  height="800lvh"
+  direction="right"
+  bind:scrollProgress
+  easing={sineInOut}
+  showDebugInfo
+>
+  <AiGraphic />
+</HorizontalScroller>
+
+<style lang="scss">
+  #horizontal-stack {
+    display: flex;
+    flex-direction: row;
+    align-items: center;
+    justify-content: space-around;
+    gap: 10vw;
+    height: 100%;
+  }
+</style>
+```
+
+## With ScrollerBase
+
+You can also integrate HorizontalScroller with `ScrollerBase` for a horizontal scroll with vertical captions experience.
+
+[Demo](?path=/story/components-graphics-horizontalscroller--scrollable-ai-2-svelte)
+
+```svelte
+<script lang="ts">

+  import { circInOut } from 'svelte/easing';
+
+  // Optional: Bind your own variables to use them in your code.
+  let count = $state(1);
+  let index = $state(0);
+  let offset = $state(0);
