Question 1

How to customize tooltips in D3plus?

Accepted Answer

Use the 'title' or 'tooltipConfig' properties in the config object to define custom content or styling. For React, override via D3plusContext or per-component props, leveraging D3's event handling for interactivity.

Question 2

D3plus vs Chart.js for data dashboards?

Accepted Answer

D3plus offers more flexibility and customization with D3's power, ideal for complex, interactive visualizations. Chart.js is better for quick, simple charts with built-in themes and smaller bundle sizes, but less control over SVG.

Question 3

Can D3plus handle real-time data updates efficiently?

Accepted Answer

Yes, but performance depends on dataset size and chart type. Since it's SVG-based, frequent updates might cause lag with large data; optimize using D3's data-binding patterns or throttle updates for smoother rendering.

Question 4

Is D3plus compatible with Vue.js or Angular?

Accepted Answer

While D3plus has dedicated React components, the vanilla JavaScript version works with any framework. For Vue or Angular, you'll need to manually wrap D3plus instances, as there are no official bindings like for React.

Question 5

What's the bundle size impact of using D3plus?

Accepted Answer

It varies by packages used; core D3plus with D3 dependencies can be several hundred KB. Use modular imports to reduce size, but it's generally heavier than lightweight alternatives like Recharts or Chart.js.

Question 6

How to export D3plus charts as images for reports?

Accepted Answer

Use the @d3plus/export package to convert SVG elements to PNG or JPEG. Call the export function with the chart's DOM node, and it handles rasterization and download, as noted in the export capabilities.
