Interactive Data Visualisation with Opus 5 and D3

X postLee Knowlton4 August 2026Demo

Lee Knowlton prompted the AI model Opus 5 with a dataset of certified running streaks to build a D3 visualisation, yielding an interactive map and multiple analytical charts.

Key points

The author provided Opus 5 with a dataset covering certified running streaks, including his own.
The prompt instructed the model to create a data visualisation using D3.
Opus 5 produced an interactive global map, a lifespan running graph, and analyses of start and end dates.

Why it matters

The demo highlights the capability of advanced frontier models like Opus 5 to ingest raw datasets and autonomously generate working, complex interactive frontend charts.

Analysis

Large language models are moving beyond basic code snippets to architecting full visual exploration dashboards. Knowlton's test demonstrates that Opus 5 can handle multi-faceted geographic and temporal data using D3 with minimal human scaffolding.

I gave Opus 5 a dataset of every certified running streak (including my own) and told it to use D3 to make a striking data visualization. It made an interactive global map, lifespan running graph, start/end date analysis, and much more. Incredible. (approach and links below) t.co/wlx6ZhbvNw
