Summary of Changes

Hello @daniela-mateescu, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a significant enhancement to the timeline component by adding a live-updating 'now' marker. This feature provides users with a dynamic visual indicator of the current time, automatically adjusting its position and scrolling the timeline to ensure it remains in view. The implementation involves a new dedicated component for the marker and integration with the existing scrolling mechanism, improving the overall user experience for real-time data visualization.

Highlights

• New Feature: Live Now Marker Update: Introduced a new nowMarkerLiveUpdate property that enables the 'now' marker to update its position in real-time on the timeline. This feature automatically scrolls the timeline to keep the marker visible.
• New Component: NowMarker: A dedicated NowMarker React component was created to encapsulate the logic for rendering and updating the 'now' marker. It manages its own timer for live updates and calculates its position based on the current time.
• BackgroundLayer Integration: The BackgroundLayer component was refactored to utilize the new NowMarker component, passing necessary props like liveUpdate and liveUpdateInterval.
• Scrollbar Enhancements: The Scrollbar component received a new scrollWithPxDelta method, allowing for direct pixel-based scrolling, which is used by the NowMarker to maintain its visibility.
• Demo Application Update: The demo application (demo-app/src/demo.js) was updated to include controls for enabling/disabling the live now marker update and setting its update interval, along with adjusted default timeline dates to center around the current time.

Code Review

This pull request introduces a live update feature for the 'now' marker, allowing it to move in real-time and automatically scroll the timeline. The implementation is well-structured, notably by refactoring the marker logic into a new NowMarker component. The changes also include updates to the demo application to demonstrate this new functionality.

My review includes a few suggestions for improvement:

• Renaming a method in the demo for better clarity.
• Correcting a discrepancy in a JSDoc comment.
• Removing an unused property from the new NowMarker component.

Overall, this is a great addition to the component's functionality.

The method name nowMarkerLiveUpdateEnabled is a bit misleading as it sounds like a getter, but it's actually a handler that toggles a state property. A more descriptive name like toggleNowMarkerLiveUpdate would improve clarity. You'll also need to update the name in the constructor binding (line 74) and the onChange handler in the JSX (line 411).

Suggested change

	nowMarkerLiveUpdateEnabled() {
	this.setState({ nowMarkerLiveUpdateEnabled: !this.state.nowMarkerLiveUpdateEnabled });
	}
	toggleNowMarkerLiveUpdate() {
	this.setState({ nowMarkerLiveUpdateEnabled: !this.state.nowMarkerLiveUpdateEnabled });
	}

The comment for liveUpdateInterval is incorrect. It states Defaults to 3 minutes (5 * 60 * 1000), but 5 * 60 * 1000 is 5 minutes. The default value is correctly set to 3 minutes. Please update the comment for accuracy.

Suggested change

	* Interval in milliseconds for live updates. Defaults to 3 minutes (5 * 60 * 1000).
	* Interval in milliseconds for live updates. Defaults to 3 minutes.

The nowMarker property is defined in defaultProps but is not used within the NowMarker component, nor is it defined in propTypes. It seems to be a leftover from refactoring and should be removed to avoid confusion.
