Isobars are similar to the level lines on a topographic map, showing areas of similar pressure, they are also drawn in circles to represent the areas of similar air pressure over a geographical map.
Isotherms are usually displayed in color showing areas over a map that have the same temperature or are covered by a similar temperature system (heat or cold front for example).
Both are used in electronic media mostly (although in print in newspapers too), over a geographic map to position the systems.
