A lightweight D3.js plugin for adding customizable context menus to data visualizations.
d3-context-menu is a plugin for D3.js that allows developers to add interactive right-click context menus to their data visualizations. It solves the problem of providing additional user interactions—like editing, deleting, or inspecting data points—directly within charts and graphs. The plugin integrates seamlessly with D3's data-binding model, making it easy to attach menus to SVG elements.
Data visualization developers and engineers using D3.js who need to enhance their interactive charts with contextual actions. It is particularly useful for those building dashboards, analytical tools, or complex visualizations requiring user input.
Developers choose d3-context-menu because it is lightweight, follows D3.js conventions, and offers extensive customization without external dependencies. Its flexibility in handling dynamic menus, nested structures, and custom styling makes it a robust solution for adding right-click functionality.

Built entirely in the D3.js style, it attaches easily to SVG elements via event handlers like .on('contextmenu', d3.contextMenu(menu)), ensuring smooth data-binding and interaction.
Supports headers, dividers, nested submenus, dynamic titles based on data, and custom CSS theming, allowing menus to adapt to complex visualization needs.
Includes onOpen and onClose callbacks for pre-show and post-show logic, enabling developers to trigger actions like closing tooltips or performing cleanup.
Menu definitions can be functions that return different items based on data, making it context-sensitive and ideal for interactive dashboards.
No default themes are provided; users must write custom CSS to style menus, as highlighted in the theme support section where it states 'make sure to style it'.
Differences between D3 5.x and 6.x affect callback arguments (event vs. index), requiring code adjustments and potentially causing breaking changes, as noted in the README.
The README does not mention built-in support for keyboard navigation or screen readers, which are crucial for accessible web applications and may require extra development effort.
