The chart below shows the minimum temperature (in Celsius) at Chattogram and Rajshahi in the years between 1997 and 2001. Describe the chart in 150 words. You should highlight and summarize the information given in the chart.

The chart provides the information about the minimum-temperature in Rajshahi and Chattogram in the years between 1997 and 2001. A picture of rise and fall in the temperature is noticed in the chart. In 1997, the minimum temperature in Rajshahi was $14^{\circ} \mathrm{C}$. For Chattogram it was only $8^{\circ} \mathrm{C}$. Next year (1998), the minimum temperature of Chattogram increased to $10^{\circ} \mathrm{C}$ but it remained unchanged for Rajshahi. In 1999, a slight increase is noticed in the minimum temperature in both Rajshahi and Chattogram. This year the minimum temperature of Rajshahi increased to $15^{\circ} \mathrm{C}$ which remained the same in 2000. On the other hand, in 1999, the minimum temperature of Chattogram increased to $11^{\circ} \mathrm{C}$, but in 2000 , it decreased to $10^{\circ} \mathrm{C}$. Finally in 2001, the minimum temperature decreased in both the regions. The bar of 2001 shows that the mipimum temperature in Rajshahi was $12^{\circ} \mathrm{C}$ and in Chattogram it was $9^{\circ} \mathrm{C}$. So, overall the graph illustrates that both the regions experienced fluctuation in terms. of temperature measurement.
