How do I explain what's happening in this graph?

There's obviously some sort of relationship between x and y, but there are also many cases when x is low and y is low. Also, a regression gives me a very low r squared value.

How would you interpret this graph. Is it likely that there are other variables impacting the dependent variable?

    $\begingroup$ You are using linear methods, but the relationship is not linear. Try to work with logarithms of the variables. $\endgroup$ – user145002 May 15 '18 at 18:29
  • $\begingroup$ See stats.stackexchange.com/a/122089/1036, your data is consistent with varying errors per the X axis variable. $\endgroup$ – Andy W May 15 '18 at 18:44
  • $\begingroup$ Without knowing the meaning and units of your variables, it's impossible to comment meaningfully on your scatterplot. $\endgroup$ – Isabella Ghement May 15 '18 at 21:59
  • $\begingroup$ The left side of the scatterplot has many more data points than shown on the right side of the plot, which will effectively weight the fit towards the data on the left rather strongly. This may not be what you want, and if possible you should consider taking more data in the region with few data points. $\endgroup$ – James Phillips May 16 '18 at 13:28
