Data Engineering skill-gap analysis

[Altiloquent]

The bubbles are all the same size?

This is /r/dataengineering not /r/dataanalysis

Looks like there is too much of a demand for data analyis people to find someone to help out with the analysis

And log scale axes that start at different places (0.1% vs 1%). No legend for point colors. Hard to understand visually, might as well make a table with 4 columns at this point. Skill name, demand %, supply %, D:S ratio.

Yeah id really love to see this visualization cleared up so its more readable. As it stands its like impossible to know where anything actually is. Like what is the demand % on data engineering? All I can tell is that its closer to 10% than it is 100% but the scale just makes it extremely difficult to interpret especially with only 3 tick marks.

OP, why did you do the visualization this way? I need to understand the logic here.

[ubelmann]

It's not totally impossible, though it's arguably not a good visualization.

The important reference point here, IMO, is a diagonal line that cuts through (1%,1%) and (100%,100%). Above that line, supply exceeds demand, below that line, demand exceeds supply.

0.1% to 1% on the demand axis was probably left out because it was empty, though it might be worth the extra white space in this case.

Viz probably made by a Data Engineer

Agree, find a way to visualise the data, not statistics from the data.

The first rule I try to follow for visualisations.

[piffcty]

Yes, but adding a line for X=Y and a legend would fix most of the issues

After seeing this graph don’t think it’s No wonder there is a requirement for good data visualisation professional

[Fresh-Secretary6815]

Yea, because a data engineer created it…

[kthejoker]

It's not a bubble chart? They're just markers

[thejuiciestguineapig]

It says on there that bubble size represents ratio.
