[NM-93] Add cascade plot

[r-ash]

Description

We want to add a cascade plot into the app. Cascade plot shows 95-95-95 targets (95% of people living with HIV are aware of the status, 95% of those aware are on treatment and 95% of those on treatment are virally suppressed)

At the moment we don't have viral suppression data from the model, but this shows the first 3 bars of the cascade. In the future we'd also like to add this as a plot of proportions instead of just pure counts.

Type of version change

Minor

Checklist

• I have incremented version number, or version needs no increment
• The build passed successfully, or failed because of ADR tests

Add cascade plot with proportions

Noticed something when playing with the filters running locally and wondering if this is expected behavior or not: If you have area level set to country, then drill down into the area filter and turn off a single district (or any other sub-level), you get the no data available message. Should user be able to show some subset of data at the country level for example, or is this working as intended?

Yes working as intended, but I do agree it is not the best behaviour. So this is the same also as how we do it in the Choropleth, you'll similar get a no data message. We've talked about addressing this before by greying out options in the drop down which would lead to no data being shown. But we've never got around to it, I think it will be quite fiddly to implement and I am not super convinced having greyed out options is much better.

So something to address across all plots down the line I think. Let me know if you have any good ideas of how we can make this a bit of a nicer user experience.
