Chapter 5 HANDLING DATA-LOADING ERRORS
Regarding global variable dataset, I found I had to define var dataset = [], and use dataset.push(data). If I did the same as the book, the dataset can only have the last element in the imported csv file.
@zlw8844 Thanks! Which specific example are you referring to? It would be helpful to have the filename (like chapter_01/00_example.html) as well as the book page number that refers to it.

I am reading the online version, and there is no page number. It is in chapter 5, section 'HANDLING DATA-LOADING ERRORS'. A snapshot of the code is as follows. I need to use an array for dataset, and push new data into it in order to save all input data into dataset. I guess it was caused by the version of D3 used?
Thanks. Where are you finding the online version? Please share a URL.
I suspect you may be referencing an older version of the text.
I read the 2nd edition through O'reilly. The link is as follows: https://learning.oreilly.com/library/view/interactive-data-visualization/9781491921296/ Regards, Lingwei "Eric" Zhan

Ah thanks.
Yes, that was my silly example. You don't have to push data into the array the way I did, but you do have to use an array.
Which version of D3 are you using with the example code? (The examples are only guaranteed with work with D3 v4.5.0, as included in this repo. If you are using v5.0 or newer, then yes, the way the CSV method works has changed, so that probably is breaking here.)
