Summary of ChangesHello @igor-holt, 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 significantly improves the user experience of the telemetry chart by replacing the default tooltip with a custom, information-rich version. Users can now gain a deeper understanding of each data point by viewing comprehensive event details directly on hover, moving beyond a simple probability display to include critical contextual information like event type, prediction mode, and outcome, along with a unique subjective description.

Code Review
The pull request introduces a custom tooltip for the telemetry chart, enhancing the user experience by providing more detailed information on hover. The changes involve creating a CustomTooltip component in TelemetryTimeline.tsx and updating getProbabilityData in data/telemetry.ts to include additional data points for the tooltip. The implementation looks good and addresses the stated objective.

The CustomTooltip component uses any for its props. It's best practice in TypeScript to define a proper interface for the props to ensure type safety and better code maintainability. This will help catch potential errors during development and improve code readability.

The label is conditionally converted to a UTC string. If label is null or undefined, an empty string is rendered. It might be more robust to provide a default or fallback text, or handle the case where label is not present more explicitly, especially if label is expected to always be a date.

Inline styles are used extensively within the CustomTooltip component. While this works, it can make the component harder to maintain and reuse. Consider extracting these styles into a CSS module or a styled-components approach for better organization and separation of concerns. This also improves readability and makes it easier to manage responsive design or theme changes.

The getProbabilityData function is now returning more fields. It would be beneficial to update the TelemetryEntry interface in data/types.ts to reflect these new fields. This ensures type consistency across the application and leverages TypeScript's benefits fully.

Changes:
- Extended
getProbabilityData()to include event, mode, outcome, subjective, and utc fields in addition to probability - Implemented
CustomTooltipcomponent with detailed formatting and styling for enhanced hover information - Added error.png binary file (appears unrelated to the PR's stated purpose)

The probability value is displayed without formatting. Consider formatting it as a percentage or with a fixed number of decimal places for consistency and better readability. For example: {(data.probability * 100).toFixed(1)}% or {data.probability.toFixed(2)}.
| Probability: {data.probability} | |
| Probability: {(data.probability * 100).toFixed(1)}% |

The TooltipProps type is imported from 'recharts' but never used. The CustomTooltip function uses any type instead. Remove this unused import or apply the proper typing to the CustomTooltip function.

The CustomTooltip function uses any type for its parameters, which bypasses TypeScript's type safety. Consider using proper typing with the imported TooltipProps type from recharts, or define a specific type based on the expected payload structure.

The tooltip lacks proper accessibility features. While the PR description mentions "clear typography and labels," the tooltip div should include ARIA attributes for screen reader support. Consider adding role="tooltip" and aria-live="polite" to ensure assistive technologies can properly announce the tooltip content.

💡 What: Added a custom, detailed tooltip to the telemetry chart.
🎯 Why: Users needed more context on hover (Event type, Prediction Mode, Outcome) and the "subjective" description adds a nice touch of delight.
📸 Before/After: The default tooltip showed only probability; now it shows full event details.
♿ Accessibility: The tooltip uses clear typography and labels.
