To create a Gantt-style chart using D3.js, you will need to draw it yourself. Start by setting up the axes and adding them to an SVG. Next, convert your data into rectangles that represent different tasks or time blocks on the chart. Label each rectangle with the corresponding data name.
D3.js does not have a built-in layout for Gantt charts, so you will have to implement this customization from scratch. If you are new to creating bar charts or working with D3.js, it's recommended to go through some tutorials like Let’s Make a Bar Chart, Parts I, II, and III before diving into this project.
While there are other libraries like C3 that offer prefabricated charts similar to D3 layouts, finding one specifically designed for Gantt-style charts may be challenging. You can explore examples like this Gantt chart which demonstrates a random task allocation across various time scales.
If you prefer a more calendar-like approach, check out the example provided at: https://github.com/dlamblin/timeblocks. This example showcases how you can adapt D3.js for different data formatting needs while maintaining a visually appealing design.
For a simplified JSfiddle example demonstrating a vertical layout of scheduled time blocks over a 7-day week, follow this link: JSfiddle Example.
The provided JavaScript snippet offers insights into structuring and updating the Gantt-style chart effectively. It includes functions for updating scales, rendering data elements, transitioning animations, and managing axes for improved visualization.
