COVID-19 status by country

Hi,

I am not really satisfied with the "COVID overviews by country" I can find on the internet.
(the best one I think = https://www.worldometers.info/coronavirus/#countries )

They fail to properly reflect the current situation and how it is evolving in the last weeks.
The issues they have is:

  • give absolute numbers instead of relative numbers in terms of population size
  • give day statistics which are fluctuating a lot during a week (e.g. less testing and reporting is done during the weekend)
  • don't give a proper indication of the current situation
  • don't make it clear how it is evolving over the last couple of weeks
  • don't make it easy to properly compare between countries

Following flow/project tries to address these points:

Note that unlike my other covid-19 related node-red flows this one is pretty light weight. So I would expect that you can deploy it without much trouble.

Here an example of the output it produced today:

If you press on the info button you will also get the documentation for the different columns:

I recommend to sort on the 2nd column "cases/day/million" in descending order.

As always ... any feedback, comments, remarks, suggestions are more than welcome.
Jan.

@janvda Jan, none of the RN sorts seem to work properly.

Hi Paul,

That is very true comment. It also proves that you have succeeded in running the flow :+1: :slight_smile:
The issue is that I am making use of node-red-node-ui-table and in order to set the background in the proper color I am feeding the cells with the actual html code. E.g.

<div style='background-color: rgb(255,36,0)'>1.86</div>`

So, I think that the node is no longer sorting on the value but on the actual html string I am providing as input.

I don't know if there is a way to fix this.

You can use a template node and create the table descriptions there. And take a look at the tabulator documentation

I had a closer look at it. It is not fully clear what you have in mind. I can remove the surrounding html tag that is setting the background color this will assure that sorting is working but then of course without any background color :crying_cat_face: .

I have found a workaround (hack) for the sorting on the Reproduction number columns. So now this is working.

I added a class tag (J00116 in the example below) with sole purpose to assure that alphabetically sorting is same as sorting on the value:

E.g. <div class='J00116' style='background-color: rgb(255,214,0)'>1.16</div>

UPDATE 2020-06-23 : updated flow below - it now contains the full flow instead of only the node that I changed.

Nicely done! - note all that is in the last flow is the one change node not the full flow. I just popped it into the flow replacing the other change node.

I'm suprised that there isn't a deaths column.

Stupid me - I updated the post with the full flow - thanks for the comment.

That is indeed a possible extension. For the moment I am focusing on the confirmed cases as they are a better indicator of the current status (deaths are following confirmed cases with a delay of weeks).

NEW FEATURE: "Distance Column added"

So it is now possible to select a country, and the flow will then calculate the distance for all countries to the selected country based on the latitude/longitude formulas described at https://www.movable-type.co.uk/scripts/latlong.html
This makes it possible to sort the list based on proximity to a selected country.

The flow:

Here below a chart where "United Kingdom" is selected and we have sorted according increasing distance:

Weirdly, this is all I see when I load the tool in dashboard?

Did you press the 'Retreive' button?

Maybe this is because you need to install node node-red-node-ui-table.

I would suggest to install this node... and if this is not sufficient then throw away the flow and add the flow again.

Already installed :frowning:

yep!

did you try the part after the 3 points ?

I just tested it using the latest version I have posted in post 9= COVID-19 status by country and this is working for me.

yep. I did. Thanks. To be honest I think there's something odd going on with my dashboard because this also doesn't load properly for me. I suspect there's something intrinsic missing from my dashboard install that's causing these two problems. Haven't a clue where to begin debugging though!

I tried it last night and got the same result as @dclear.
I noticed that the table size was ringed in red as though it was having a problem with the size.
I didn't have time to look further, so I deleted the flow.
So yes, I can confirm the problem.

@Paul-Reed, @dclear

  • what browser are you using?
  • is the machine running NR the same one the browser is on?
  • what machine is NR running on?
  • What version is NR and node.js?

I'm running NR on a mac and Safari, Chrome and FireFow all work.
I then installed the flow on a Pi3 model-B (Buster) and accessed it via the browser on my mac and it works fine

@janvda - a thought, how about a column showing the one day change in RN?

@zenofmud

  • what browser are you using?
    Chrome Version 83.0.4103.106 (Official Build) (64-bit)

  • is the machine running NR the same one the browser is on?
    No

  • what machine is NR running on?
    NR running in Oracle cloud VM, on Oracle Linux 4.14

  • What version is NR and node.js?
    Node-RED version: v1.0.6
    Dashboard version 2.22.1
    Node.js version: v10.20.1

I think I managed to reproduce the issue.
To fix this I had to do 2 things:

  1. Assure that the table node is set to the right Group:

  2. I also had to restart my node-red docker container (just redeploying the flow didn't fix it). I guess that restarting node-red is sufficient. (I think this is needed in case you install node-red-node-ui-table via the "manage palette" menu).

Sorry Paul, not fully clear what you mean by one day change in RN. You mean the difference between column 4 and 5 ?

Upon importing the flow the table group was set correctly - [COVID19 - country overview] table, but reselected (the same group) again, deploy, and thereafter the flow worked OK.
Nice work @janvda
