How do I embed an interactive chart in a Beehiiv post?
Quick answer
Unlike Substack, Beehiiv supports iframe embeds via the HTML content block — meaning any chart tool that generates embed code works interactively, including Quadesto, Datawrapper, and TradingView. Add an HTML block in the editor, paste the iframe code, and the chart renders with full interactivity in the published newsletter.
Beehiiv's growing finance audience
Beehiiv has emerged as a serious alternative to Substack for newsletter writers, particularly in finance and business. Its monetization tools, referral programs, and analytics are more sophisticated than Substack's, which is attracting finance writers who treat their newsletter as a business.
But Beehiiv has fewer native integrations than Substack. There's no built-in TradingView widget. No auto-detection of Datawrapper URLs. Everything goes through Beehiiv's HTML block or their /embed command.
How embeds work in Beehiiv
Beehiiv supports two embed methods:
1. The /embed command: Type /embed in the editor, paste any URL, and Beehiiv tries to render it as a rich embed. This works for YouTube, Twitter, and some chart tools.
2. The HTML block: Add a custom HTML block and paste iframe code directly. This works for any embeddable content, including Quadesto, Datawrapper, and TradingView.
For Quadesto charts, the HTML block method is the most reliable:
1. Create your chart in Quadesto
2. Click 'Share' → 'Embed code'
3. Copy the iframe code
4. In Beehiiv, add an 'HTML' content block
5. Paste the iframe code
The chart renders interactively in both the preview and the published newsletter.
Responsive sizing
Set the iframe width to '100%' and height to '500' (or adjust based on your chart). Quadesto embeds handle resize events automatically, so the chart adapts to any screen size including mobile.
Why Beehiiv writers choose Quadesto
Beehiiv newsletters tend to be more analytically rigorous than average — the platform attracts writers who care about data. Quadesto's finance-specific chart types give these writers visual tools that match their analytical depth:
• Yield curve analysis for macro newsletters
• Options analytics for derivatives-focused content
• Candlestick charts with technical indicators for market commentary
• Economic data visualization from FRED for policy analysis
The combination of Beehiiv's business tools and Quadesto's visualization depth creates a powerful stack for finance content creators.
