13. Conclusion

We began this book with a quick look at a standard approach to writing a D3 chart. If you've reached this far in the book, and you've read it all, nicely done! Hopefully we've opened your eyes to a much more sustainable and reusable method to using D3.js, and how powerful D3.js applications can be.

We had a number of intentions in mind when writing this book:

• Give greater understanding to some of the core patterns that lie at the very heart of D3.js.
• Provide documentation and examples of how D3.js code could be written in a more reusable and sharable fashion.
• Encourage you, the reader, to do this yourself, whenever you write D3.js code.
• Help those keen to move on from a basic level of D3.js to a more intermediate-advanced level of understanding.
