Wedgetail is a small and simple profiler. It’s focus is to provide timing information for a large number of invocations of the same function. This allows you to derive meaningful statistics of the performance of that function. Wedgetail is added to your tests, and can help you ensure you’re not adding code that is dramatically slowing down your app or module.
Looking beyond D3.js? Try Chart.js for quick, elegant charts, or ApexCharts for rich interactivity and annotations. Building dashboards? boxiqq speeds layout and theming, while React pairs well with many chart libs.
