Billboard | - Transition the views as billboard

I am using the same example line chart shown here. However, I have black fill under the lines on my chart. How do I remove the black fill from under the lines. In the documentation under LineChartOptions there it only shows two configurable options, HidePoints and LinePoint. Here is my example. The same thing happens to my time series chart. Thank you.

I have this element where I want to access props and change the image or scale on hover using CSS, can anyone please guide me on how to do that and thank you.

My Dataframe: billboard_2

I need to count the number of weeks a song is on billboards by using an apply function and a simple python function. But apparently, I am not able to do so.

I managed to do it via the lambda function but I am supposed to use apply function. The output I am getting lambda function is exactly what I need using the normal function.

I need to make the arrow of the right side colorful #2b6a83

I have two csv files, one regarding Artists and one regarding Billboard 100 songs that look like this:

Artist (First 4 rows)

Billboard (First row)

Now I have to write a SQL query to print each artist along with the number of albums they have released and the number of Billboard100 songs they have, which requires me to join the two tables. My schema for the two tables looks like this:

I got stuck in a part of my code. Basically I have a list and I would like to show more info when I click on item, I have a modal and I would like to show this details on a modal. I managed to pass some information, however, when I pass the array it displays only the last item in the list and I would like to display exactly the one I clicked.

Yo yo yo. I got this insane idea to get 50 of the billboard hot 100 songs, download them into mp3 files, and then put them on private online radio.

Problem is, the way I do it doesn't download each file one by one, it puts all the music together in one mp3 file. Here's my code so far (terrible, I know... I just wanna throw this together really quickly)

I wonder why ramda's map-function is not behaving as I would like i.e. 'dataAllAgesAllF' is an Object of more than 5 key-value pairs and I would like to choose only those key-value pairs that match the keys of 'ageGroupData'. The list line prints out nicely the 5 correct keys and the map-line works if I write explicitly x[ageGroupFNames[0]] instead of the arrow function

I've been following along with the Tidyr official documentation, trying to freshen up on it because I haven't used it in awhile.

One of the examples involving the billboard dataset produces the following error:
