D3 allows you to bind arbitrary data to a Document Object Model (DOM), and then apply data-driven transformations to the document. For example, you can use D3 to generate an HTML table from an array of numbers. Or, use the same data to create an interactive SVG bar chart with smooth transitions and interaction.

D3 is not a monolithic framework that seeks to provide every conceivable feature. Instead, D3 solves the crux of the problem: efficient manipulation of documents based on data. This avoids proprietary representation and affords extraordinary flexibility, exposing the full capabilities of web standards such as HTML, SVG, and CSS. With minimal overhead, D3 is extremely fast, supporting large datasets and dynamic behaviors for interaction and animation. D3’s functional style allows code reuse through a diverse collection of official and community-developed modules.

6 JavaScript Charting Libraries for Powerful Data Visualizations in 2023
Depending on your requirements, the best JavaScript library is D3.js, as it’s by far the most customizable. However, it’s also really complex and difficult to master.

If you’d prefer a less complex library that you can use with TypeScript, ECharts, and...

The Best 24 Appointment Scheduling Apps and Booking Software
I have frequently used Calendly in the past, primarily for scheduling job interviews. What I appreciate about Calendly is that the free version still allows you to connect one calendar, book unlimited meetings, create a custom Calendly link, and send out automatic email notifications and reminders to invitees who book with you.
neetoCal, a calendly alternative, is a commodity and is priced accordingly
neetoCal is not the first company to compete with Calendly. We are not even the second company to compete with Calendly. We are probably the 30th player in this crowded space. With so many players in the market, scheduling software seems like a commodity.
