API to generate charts in PNG/SVG/HTML
Hi people, I've been working on this API for sometime now and I thought others might find it interesting. The API is available on rapidapi @ https://rapidapi.com/formkiq/api/24hourcharts This API allows you create bar/line/pie/etc charts in a single API call. The only required fields are the type of chart and a list of data points to chart. There are many ways to create charts, but I've found most charting solutions only work inside the application they are created in. I was looking for a solution that allows me to use/create/share charts…
In plain words
This API generates bar, line, pie, and other chart types in PNG, SVG, or HTML format with a single call, requiring only the chart type and data points. It's designed for developers who need to create and share charts outside their application environment without being locked into a specific tool. The service offers a free tier allowing 100 requests daily, with future plans to integrate with services like Notion.

Hi people, I've been working on this API for sometime now and I thought others might find it interesting. The API is available on rapidapi @ https://rapidapi.com/formkiq/api/24hourcharts This API allows you create bar/line/pie/etc charts in a single API call. The only required fields are the type of chart and a list of data points to chart. There are many ways to create charts, but I've found most charting solutions only work inside the application they are created in. I was looking for a solution that allows me to use/create/share charts however I want easily. In the future I really want to focus on being able to simply integrate with other service like notion. There's a free plan that allows you to make 100 requests per day. Hope you'll find it useful. Let me know if you have any comments or features for me to add next.

History: Last year I had to replace the tire on my bike, and I was surprised how difficult it was to find a suitable new tire. There were a lot of numbers written on the casing, so I googled what they meant. In the end I was successful, but I didn't want to do the same work again for the next bike after I've forgotten the details. So I wrote this website. Technically, the web page is kept very simple, no frameworks, no templates, no website builder. It uses HTML5, CSS and JavaScript, and it privides a responsive layout for mobile usage. I'm happy to receive feedback. If you have tried the…
