Isopleth or level line (from the ancient Greek "equal") is a symbol on the map, drawing, diagram or graph, which represents a line at each point of which the measured rate retains the same value.

The subject/technique of nonlinear connections and plexuses acquire other meanings from work to work. Paintings from the "Izolines" series work with a new, third dimension. The works, preliminary-reproducing "expansion", "spreading", and "growth" on the plane ("rhizomes"), now manipulate with the "leveling" ("iso" – from the ancient Greek "equal"). Canvases like the maps of tectonic or meteorological indicators are filled with isolines: isopleths, isobars, isotherms...

For the artist, the process of her creativity is a continuous process of "questions and answers", where each line is a fixed moment of finding the truth. Layer stacking and multi-leveledness are another scale for measuring this constant movement.
