A circle is divided into parts. No axes are necessary. It shows how the whole is divided into parts. It usually does not give details. It is easy to compare the size of categories. Uncomplicated and takes up little space.

It is easy to read and understand. It is easy to draw. Two axes are used. It is impressive in appearance. It allows comparisons to be made at a glance. It shows more detail than most graphs.

It is more attractive than most graphs. It does not give detailed information. It allows us to compare the sizes of each category easily. Only one axis is necessary. It is easy to understand.

It shows more detail than most graphs. All points on the line should have some meaning. Each point has a reading on both axes. A line is used to show trends and relationships clearly. Two axes are used.

No axes are necessary. Uncomplicated and takes up little space. It shows how the whole is divided into parts. It usually does not give details. It is easy to compare the size of categories. A rectangle is divided into parts.

There are many routes you could take. One is shown in blue on the map.

Birdcage Walk is a long road passing through A4, B4, B3, C3 and D3. You would need an address on the road to help locate a position more closely.

The gardens are almost rectangular:

Area of rectangle ! 150 m × 100 m about 15 000 m2
b
by road – about 1200 m (1.2 km)
You could also use a fraction of a grid square to estimate the area. Area of 1 grid square = 200 m × 200 m = 40 000 m2 The park fills a bit less than half a square so it has an area of a bit less than 20 000 m2.
