node map icon png download

The image of the bottom of "basket 02". "basket 02" is composed of 7 path-layers. I removed 2 path-layers and recolored each path-layer. This clipart is only the bottom of the original basket because I cut 4 sides. To cut ,I used Path>Difference. for overlap,I created a rectangle.Each time I do Difference,the rectangle disappears.So, totally,created 20 rectangles and did Difference 20 times. I did not know how to call lines like contour -line. So,I called it "node map". Thanks.
