Code Review
The pull request introduces several valuable enhancements to the Telemetry Timeline component, including a custom tooltip for better data interpretation, improved accessibility for the data table, and an empty state handling for when no telemetry data is available. These changes significantly improve the user experience and accessibility of the component. The pnpm-lock.yaml file was also updated, likely due to dependency changes related to these new features.

It's good practice to define a type/interface for the CustomTooltip props instead of using any for better type safety and readability. This helps in understanding what properties active, payload, and label are expected to have.

The telemetryData variable is directly accessed here. While it works, it might be more consistent and maintainable to pass telemetryData as a prop to the TelemetryTimeline component, or fetch it within the component if it's dynamic. This makes the component more reusable and testable.

Adding scope="col" to table headers is a great accessibility improvement. This helps screen readers understand the structure of the table.

| <td scope="row" style={{ padding: '10px' }}>{entry.logId}</td> |

Adding scope="row" to the Log ID column is also a good accessibility practice, ensuring screen readers correctly associate the row header with its data cells.

Adding event and mode to the getProbabilityData return object is a good change, as it makes this data available for the custom tooltip, enhancing the chart's interactivity and information display.

The CustomTooltip component uses the any type for its props, which bypasses TypeScript's type safety. Consider defining a proper interface for the tooltip props. Recharts provides TooltipProps type that can be used, or you can define a custom interface specifying the shape of active, payload, and label parameters to improve type safety and code maintainability.
| const CustomTooltip = ({ active, payload, label }: any) => { | |
| import type { TooltipProps } from 'recharts'; | |
| const CustomTooltip: React.FC<TooltipProps<number, string>> = ({ active, payload, label }) => { |

| <tr key={entry.logId} style={{ borderBottom: '1px solid #ddd' }}> | ||

| <td scope="row" style={{ padding: '10px' }}>{entry.logId}</td> |

The scope="row" attribute is incorrectly applied to a table data cell (td). The scope attribute is only valid on table header cells (th elements). For row headers, you should use a th element with scope="row" instead of a td element. This is important for screen readers to properly associate the row header with the data cells in the row.
| <td scope="row" style={{ padding: '10px' }}>{entry.logId}</td> | |
| <th scope="row" style={{ padding: '10px' }}>{entry.logId}</th> |

The empty state check uses telemetryData.length === 0 but the chart is rendered using chartData from getProbabilityData(). While these are currently equivalent, there's a logical inconsistency. The component should check the same data source that it displays. Consider using chartData.length === 0 for consistency, or checking both if there's a specific reason to check the raw data.

💡 What: Added a custom tooltip to the Telemetry Timeline chart, improved table accessibility, and added an empty state for the data.
🎯 Why:
scopeattributes, which are crucial for screen readers to associate headers with data cells.📸 Before/After:
