Statistical and engineering charts

  • Histograms, error bars, box plots, and 3d surface plots. Plotly.js is the only JavaScript charting library bringing science and engineering visualization to your browser.

Performance: Using WebGL for the Fastest Load Times with the Most Points

  • Plotly.js WebGL charts with 1 million points load 1.6x faster than the same Highcharts graph, even with the Highcharts “booster” library. We’ve optimized everything from min-max decimation to numerical type checking. The Plotly.js WebGL backend uses your computer’s graphics card to bypass CPU and memory limitations in SVG or Canvas graphics backends.
Performance Benchmark

Note: The above comparisons use the total rendering time as the benchmark. Highcharts uses an async renderer as an optional paid add-on, which makes a few points appear on the graph in 0.2 seconds, whereas plotly.js plots everything at once. Full discussion.

D3.js and Stack.gl: Stand on the shoulders of Giants

  • Plotly.js’s SVG backend uses D3.js, the gold standard of SVG graphics for the Web. D3.js is challenging to learn however and time-consuming for even JavaScript experts. With Plotly.js now even a JavaScript beginner can create performance optimized, insanely complex D3.js charts in minutes.
