Yes, it is possible to create a bubble chart without having the bubbles overlap each other. Here are the steps to do it:

1. First, select the data that you want to use for your bubble chart. Make sure that you have three columns of data: one for the x-axis, one for the y-axis, and one for the size of the bubbles.
2. Next, insert a new chart by clicking on the "Insert" tab and selecting "Bubble Chart" from the "Charts" section.
3. Once you have inserted the chart, right-click on one of the bubbles and select "Format Data Series" from the drop-down menu.
4. In the "Format Data Series" pane, select "Fill & Line" and then choose "No Fill" for the fill color. This will make the bubbles transparent.
5. Next, select "Marker Options" and then choose a shape for the bubbles that is easy to see, such as a circle or square.
6. Under "Marker Options," select "Size" and then choose a size for the bubbles that is appropriate for your data.
7. Finally, adjust the spacing between the bubbles by selecting "Layout" and then choosing "Spacing." Increase the spacing until the bubbles are no longer overlapping.

By following these steps, you can create a bubble chart that displays your data without having the bubbles overlap each other.
