The line chart delineates two factors which are demand for steel and the number of workers employed in a country in a span of a year, where steel production is in million tonnes and the workers only in thousands.
Overall, both show nearly similar pattern with peak at some points and being plummeted by the end of the year.
There is always over-exploitation in human activities and it can be seen by the line graph about how many tonnes of steel was produced against the actual demand. At the start of the year actual demand was 2000 million tonnes whereas, the production amount at that time was double then the need. Between January and April both the need and production fired up by a million tonnes. Though, after this the production saw a consistent production of 4000 million tonnes whereas, the actual demand saw a decreasing trend and went just below the 2000 million tonnes threshold. Even though, the amount of making was persistent the demand saw dynamic trend reaching nearly 3000 and then going below 2000 again in August. After that the production again saw its pinnacle with 5000 and demand rose with it as well again reaching nearly again mark of 3000. Although the demand was always inferior in December sides switched and demand rose more than the production.
Similarly, the number of workers in the start of the year 5000 workers were employed, the number fell to 3000 just before reaching April. After April it illustrated the most fluctuations by rising to nearly 3500 and then falling back to 3000 again. In August it showed the second highest peak after January reaching nearly 4000. Though, the trend declined constantly by the December and, in December it showed 3000 workers less employed than August.
