Below is a plot of the sizes of planets and the Sun in the solar system. On the vertical axis the points are arranged using a linear scale, and you can see that points are all bunched up in one small region near the bottom of the plot, and there is an outlier point (the Sun) near the top. In contrast, the horizontal axis uses a logarithmic scale, and you can see that the points are more evenly spread out.
Because the points are more spread out, there are more regular distances between points of interest. It is therefore more instructive to view this data using a logarithmic scale, or for example in a view window with an exponentially growing zoom.
In the following diagram, as you use the slider to adjust the zoom, you will notice that with linear scaling, the planets are all visible only for quite a small subset of the scale values. If you switch to logarithmic scaling, the planets are visible for a greater proportion of the possible slider values.
