The ability to load items in a data grid as you scroll is a technique where content is rendered or fetched dynamically based on the user’s scroll position. Its purpose is to improve performance, and ultimately the user experience, when dealing with large datasets. This includes virtual scrolling, where the grid only renders rows that are currently visible in the viewport and reuses those same DOM elements as the user scrolls, and infinite scrolling (also known as endless scrolling), where additional data is loaded from a remote source in response to reaching the end of the currently displayed dataset. By minimizing the amount of data rendered or retrieved at any one time, this approach significantly reduces initial load times, improves responsiveness, and allows applications to scale efficiently.

Several JavaScript grid components allow you to load items as the user scrolls, including:

• DevExtreme HTML5 JavaScript Data Grid (part of DevExtreme by DevExpress) supports both virtual and infinite scrolling to optimize data loading performance.
• KendoReact Data Grid (part of KendoReact by Telerik) offers customizable column/row virtualization and virtual scrolling, dynamically requesting data as needed.
• Sencha Ext JS Grid (part of Sencha Ext JS) implements infinite scrolling through a virtualized system that loads data on demand without traditional pagination.
• Syncfusion DataGrid for JavaScript (part of Syncfusion Essential Studio Enterprise) allows both virtualization and infinite scrolling for responsive grid rendering.

Animation in charts is a feature used in data visualization to visually transition between different data states or configurations. This technique helps communicate changes in data over time or between user interactions in a smooth, progressive manner. Rather than instantly switching from one state to another, animation introduces motion that can guide users’ attention, reinforce patterns, and reduce confusion. It is particularly useful in interactive dashboards and real-time analytics, where users benefit from a clearer understanding of what has changed and how.

Several Vue.js charting components support the use of animations, including:

• DevExtreme Chart (part of DevExtreme by DevExpress) offers high-performance Vue components for data visualization that integrate configurable animation options.
• Wijmo FlexChart and FinancialChart (part of Wijmo by MESCIUS) incorporates various animation modes and timing controls for visualizing data in web applications.
• Highcharts Core by Highsoft is a JavaScript charting library that can equip Vue.js apps with advanced animation functionality for highlighting data and aiding data interpretation.
• Kendo UI for Vue Chart (part of Kendo UI by Telerik) features built-in animations that respond to data changes in real-time, creating engaging transitions by default.
