Learn how to export Plotly figures to a single, self‑contained HTML file using offline mode, including code, verification steps, size limits, and common pitfalls.
Learn how to create a single, self‑contained HTML file from Plotly that works completely offline, with a concrete Python example, size checks, and a decision checklist.
Learn how to optimize Plotly Dash apps by distinguishing between Input and State to prevent unnecessary server round-trips and improve UI responsiveness.
Learn how to use Plotly's layout.template to eliminate redundant styling code and instantly switch between themes like plotly_dark and ggplot2 for consistent visualizations.
Want a live line chart that stays snappy? This post walks through Plotly’s streaming API, shows a minimal example, and explains how to keep updates fast by managing trace buffers and network quirks.
Plotly's default SVG rendering chokes on large scatter plots. Switching to scattergl (WebGL) is a one-line change — here's when it's worth it, what you give up, and how to verify on your own machine.
Component: Plotly.js Accessibility Layer Plotly.js utilizes SVG and WebGL rendering to generate data visualizations. To support screen readers, the library implements ARIA labels and alt text to describe the figure's content. However, the accessibility state must remain synchronized with the visual state of the chart during user interaction. When users inter
Integration Boundary: React State to Plotly.js Engine When utilizing the react-plotly.js wrapper, the library maps React props to the underlying Plotly.js engine. To maintain performance and user experience, the wrapper utilizes Plotly.react to update the plot without recreating the DOM element, which is intended to preserve the current zoom and pan state du
Goal The objective is to migrate a small Plotly.js application to a newer release without downtime. During the transition, the application may temporarily lack data when initializing charts. Constraint Plotly.newPlot throws a runtime exception – "Cannot read property 'data' of undefined" – when its first argument is undefined or null. The library documentati
