Enhancing AI-Assisted JavaScript Chart Development with Context7 MCP and Claude

November 26th, 2025 by AnyChart Team

Diagram showing Claude, Context7, and AnyChart connected with arrows, above multiple devices displaying JavaScript charts, illustrating AI-assisted data visualization developmentAt AnyChart, we are constantly exploring tools and workflows that help developers work more efficiently, stay up to date, and minimize friction when integrating data visualization into their projects.

One approach we’ve recently tested — and found highly effective — is connecting Claude to Context7 via the Model Context Protocol (MCP). This integration gives Claude access to a continuously updated, extensive database of technical documentation across libraries, packages, and APIs.

This means you can rely on Claude not just for reasoning, but also for live, accurate, and authoritative documentation retrieval, dramatically reducing the chances of outdated suggestions or hallucinated methods.

Building JS Resource Gantt Chart to Visualize Tokyo 2020 Paralympic Schedule

August 17th, 2021 by Shachee Swadia

A Mac screen with an interactive JavaScript Resource Gantt chart visualizing the Tokyo 2020 Paralympic schedule by venueSmart resource allocation is a must to achieve a high level of operational efficiency. Aiming to ensure it, project management professionals commonly rely on a special form of data visualization called a Resource Gantt chart. Creating graphics like this may seem daunting at first sight. But I am here to show you an easy way to build Resource Gantt charts with JS using a compelling, topical example.

Resource Gantt charts, also known as simply Resource charts, consist of bars oriented along the horizontal axis. Each bar visualizes a resource used by an activity, with the length representing the duration while that resource is occupied by that activity. The left and right edges of the bars display the start and end times. The resources, or event labels, are listed on the left. The dates and times are shown in the header.

Tokyo 2020 Paralympic Games are just around the corner. So, I decided to visualize their sports program by venue. Follow along with this stepwise tutorial and you will learn how to create a cool JavaScript Resource Gantt chart visualizing the Tokyo 2020 Paralympic schedule!

Create Simple Gantt Chart Using JavaScript — Tutorial

Use a JavaScript library to create a Gantt chart and take your project management efforts to the next level.

Earlier this year, my team was looking for a project management tool that could assist us in charting the various tasks related to our app development project against some specific timelines. After doing some research, we finally settled on Gantt charts. However, some people think Gantts are complicated to create. Not true! Thanks to numerous JavaScript chart libraries, data visualization is now simple, flexible, and embeddable.

In our situation, we settled on AnyChart’s JS Charts library because of its ease of use, extensive documentation, flexible code playground for trying out stuff, and other powerful features.

In this tutorial, I’ll walk you through how to create a simple interactive Gantt chart using this data visualization library. Here’s what we’ll be making and you can get the entire code for creating such a Gantt chart at the end of the tutorial:
